Vietnamese Combat Sports: Three Scoring Systems, One Classification Error

Three judges sit in three corners of the mat. Three scorecards. Three columns of numbers. The gold medal in a forms event is decided by a 0.03-point gap between two athletes — a margin smaller than the tolerance any certified sports testing laboratory would be required to declare in an inspection record. No one in the stands asks the simplest question: which system is scoring here. A few hundred metres away, inside the same complex, one combat bout ends on the scorecards of five officials. In a third arena, another bout also ends on the scorecards of five officials. Three rulebooks. Three different definitions of the word "point". Three different understandings of what a clean strike actually means. I have spent most of my career reading documents like these. Scorecards, weigh-in records, sponsorship contracts, payroll sheets, bank statements. After fourteen years, the thing I believe most firmly is this: the biggest error in combat sports media does not sit with the referees, the athletes, or the federations. It sits in the fact that we call all of it by a single name — "martial arts" — and then apply a single analytical framework to it. ONE WORD, THREE WORLDS In Vietnamese, "martial arts" is an umbrella that is far too wide. It shelters four things with fundamentally different operating logics. The first is traditional martial arts and demonstration disciplines — where results are decided by technical scoring, difficulty, and precision of movement. The second is combat under its own rulebook, most notably sanda, where points exist but are tied to the number of valid strikes and to catch-and-sweep situations. The third is boxing, where points are tied to clean, effective strikes and control of the bout. The fourth is MMA, where outcomes are usually decided by early finishes and where scorecards are merely a fallback. Those four worlds share one word. And in the press, they often share one analytical framework. This is the root of nearly every distortion I have recorded across fourteen years. When a reporter uses win-loss logic to write about a forms event, he is measuring height with a scale. When an editor uses finish rate to assess a sanda athlete, she is comparing two quantities that do not share a unit. When a commentator talks about the "form" of a forms athlete based on medal count, he is confusing the stability of a routine with the stability of competitive results. In the methodology file I have maintained since 2026, this is step zero, the step I am never permitted to skip: determine the subject class before analysing anything. Modern combat sport, traditional demonstration martial art, or sanda. Those three answers lead to three different toolkits, and no toolkit works for the other two. The stadium is spotless. The locker room is not. THREE LAYERS OF VERIFICATION From that classification error, I built a three-layer procedure for every piece I write about martial arts. It is not a ritual. It is a fence against accidentally producing a conclusion that is wrong but sounds entirely reasonable. The first layer is rule identification. Before I write a single word, I must be able to answer: under which rulebook was this bout scored, how many officials, what are the priority criteria, is there an extension round, and who holds authority to publish the final result. If I cannot answer, I do not write. Not because I lack confidence, but because every sentence after that would stand on sand. The second layer is data tracing. For every number I intend to use, I must answer three questions: who measured it, with what instrument, and in which document does it appear. For boxing and MMA, that means referee scorecards and official results sheets. For demonstration arts, it means the detailed sheets of each judge, including technical scores and deductions. For sanda, it means the record of valid strikes. The third layer is framework selection. Only once the first two layers are complete am I permitted to choose an analytical approach: head-to-head record logic, finish-rate logic, or technical-score logic. This is the layer most online content skips, and it is also the layer that produces the most false conclusions. The testing laboratory does not know the athlete's name. That is why I trust it. I learned this from a very different file. In 2026, while still a final-year student, I held a leaked document from an anti-doping laboratory. It listed 37 samples flagged for abnormal testosterone markers, all placed under review. What took me three months was not the number 37. It was understanding the testing protocol precisely enough to know what an abnormality in that document actually means within the regulatory context. Without that step, every figure is meaningless. My first article carried 47 footnotes for a two-thousand-word piece. That was not excessive caution. It was the only way an outsider could publish a conclusion about the industry without turning himself into a bad source. FRAMEWORK ERROR IN VIETNAMESE REALITY In Vietnam, the structure of martial arts makes framework error unusually easy, for three reasons. First, the competition system is spread across many different bodies. One athlete may compete in national events, regional events, international events, and invitationals, each governed by a different rulebook. Between those events, the definition of a valid strike can differ in force threshold, legal contact area, and how a caught leg is treated. Second, reporters move between disciplines constantly. A journalist assigned to boxing coverage may be sent to a traditional martial arts event the following week. The instinct is to reuse the old framework. And the old framework produces a piece that is structurally wrong even though every individual sentence is factually true. Third, public data is inconsistent. Some events publish detailed scorecards. Some publish only aggregate scores. Some publish nothing beyond a medal list. That inconsistency turns cross-discipline comparison into a trap. I once saw a comparison piece set a combat athlete against a demonstration athlete and conclude the former was "stronger" because of a higher win rate. Mathematically, the comparison is valid. In substance, it compares number of bout victories with number of high technical scores. Two quantities that share neither a unit, nor a scale, nor a mechanism of production. That is why I apply a hard rule: never use the competitive results of one class to infer anything about another class, even when both sit under the same governing body. I began an investigation with one odd figure in a payroll sheet. It ended in a room with no number. THE TIANHAI LESSON IN A MARTIAL ARTS CONTEXT In 2026, when the pandemic halted every competition, one club announced dissolution after five consecutive months of unpaid wages, affecting 28 players and 14 staff. Other reporters covered the team's disappearance. I obtained a financial statement from a former executive and found eleven million yuan moving through three shell subsidiaries with no real operations. It took me seven weeks of cross-checking against public corporate registration records before publishing. Those seven weeks were not spent finding more evidence. They were spent testing whether the evidence I already had would survive the harshest possible reading. That principle transfers intact to martial arts. When a bout ends in a controversial decision, the reflex of the press is to find a name to blame. My reflex is to find the card. Who scored it, under which criteria, and whether those criteria matched the rules published before the bout. In many cases I have handled, the difference was never that an official scored wrongly. It was that the published rule was not specific enough to decide the situation that actually occurred. In other words, the error lived in the text, not in the person. Contracts usually run one page. Dirty contracts come with an annex. This leads to the observation I consider most important in this entire piece. In combat sports, most disputes are not resolved by referee competence but by the precision of the rule text. In professional boxing, disputes usually turn on the 10-9 system and knockdown handling. In sanda, they turn on whether a caught leg counts as a scoring strike or as an escape. In demonstration arts, they turn on deduction for technical faults. Those three kinds of dispute require three kinds of investigation. And none of them resembles tracing money in a club dissolution case. So when I talk about "martial arts analysis", I must always state which layer I am analysing. If I analyse cash flow, I cannot conclude anything about competitive quality. If I analyse scorecards, I cannot conclude anything about an organisation's sustainability. This is what sports media routinely violates. WHICH DATA IS TRUSTWORTHY There is a question colleagues ask me constantly: how do you know a number is trustworthy? My answer has two parts, and the critical thing is never to mix them. Part one: is the data real. This can be tested by cross-checking at least two independent sources and by verifying whether the figure exists in an original document. If a number exists only in articles that cite each other, it is not data. It is a rumour formatted as a number. Part two: what question can that data answer. A real number can still be meaningless if it does not share a unit with the question being asked. Medal count answers a question about achievement. It does not answer a question about competitive quality under a different rulebook. Mixing those two parts is the fastest way to produce a piece that is both accurate and useless. In one project, I spent five weeks interviewing three independent sports medicine specialists about a positive test. What I needed to clarify was not the positive result — that had a written record. What I needed to clarify was the line between a declared therapeutic treatment and a regulatory violation. That line lives in medical text, not in a test conclusion. From that project, I began building a personal database of doping-related cases stretching back to 2026, sorted by substance class and medical context. Not to write about those cases. But to have a reference point when a new case appears and everyone around me already has a conclusion. THE RATIONAL CASE FOR SILENCE Here I need to defend a position many colleagues reject. When a file is incomplete, the correct choice is not to publish with caveats. The correct choice is not to publish that piece. In news, there is an invisible pressure: there must be output. A site needs traffic. A reporter needs a byline. And when data is absent, the temptation is to write about the absence of data in a way that sounds like a conclusion. I did that in my early months, and I know exactly what it produces: a piece that makes readers believe they have understood an issue when in fact they have not yet encountered it. One point must be stated plainly: an "undetermined" status is not the same as "normal". When a file contains no information, the correct conclusion is "unknown", not "no problem". Those two sentences look similar in print. They differ completely in consequence. I have seen those consequences. When media treats the silence of data as the absence of risk, organisations learn that simply publishing nothing is enough. Ambiguity becomes a strategy rather than a defect to fix. That is why I do not accept a piece built on inference, even when the inference seems logically sound. Without a document, a scorecard, or verifiable testimony, there is no piece. This rule has cost me many opportunities. It has also made everything I publish stand up. Over one year of monitoring, I decided three times not to publish. All three times, waiting was correct. WHAT REMAINS There is a structural gap in Vietnamese martial arts journalism that no technical fix will close: the people who write about martial arts are often not the people who understand martial arts rules, and the people who understand the rules often do not write. That gap produces a specific outcome. Audiences receive information about results but not about how results are produced. They know who won. They do not know why that person won in the strict technical sense of the applicable rulebook. I am not proposing that everyone writing about martial arts become a referee. I am proposing something smaller and immediately achievable: every article about a bout should state the rulebook and scoring system applied. One line. It costs no extra length. But it forces the writer to ask which layer they are analysing. Three judges in three corners will sit there again this weekend. Three columns of numbers will differ by a few percentage points. And one athlete will leave the mat with a medal while no one covering them knows precisely which system awarded it. The distance between "knowing the result" and "understanding the result" does not sit on the mat. It sits with the person writing. And that is the only link in this chain we can fix today, without waiting for any federation to change its rules. QUICK REFERENCE DATA NOTE Classification principle for the three classes in Vietnamese combat sports: Modern combat class — boxing, MMA, kickboxing, muay. Results rest mainly on win rate, finish rate, opponent quality, and official scorecards. The appropriate analytical framework is head-to-head and record logic. Combat with its own rulebook — sanda and similar. Results rest on valid strike counts and the handling of falls and caught legs. The appropriate framework is round-by-round technical scoring logic. Traditional demonstration class — forms and demonstration sparring. Results rest on technical score, difficulty, and deduction. The appropriate framework is judge-score logic, not win-loss logic. These three classes do not share a framework. Any attempt to merge them produces a conclusion that is wrong but sounds reasonable — the hardest kind of error in sports media to detect.
