The Empty Scorecard: Vietnamese Martial Arts Is Analyzing With Memory Instead of Data

There is a question I have asked over and over for five years, at venues from Ha Noi down to Can Tho: "Can I have tonight's record sheet for both fighters?" The most common answer is not a piece of paper. It is a shrug, followed by a story.

People tell me where the fighter is from, who his coach is, that he once fought in Thailand, that he once took a very painful knee, that he quit for a year and came back. Those stories are good. They are truer and richer than any line of statistics. But when the big screen switches to the tale of the tape — the comparison board every boxing night in the world carries — what appears is usually blank, or a few numbers the announcer counted from memory. Then someone fills the gap with adjectives.

I trained as a broadcaster, and the first lesson I learned had nothing to do with voice. It had to do with saying a name correctly. In 2026, at eighteen, I sat in a small studio in Incheon and mispronounced a player's name three times in the first half of Korea against Germany. The station's phone rang. I was ashamed enough to record my entire commentary, listen back sentence by sentence, and ask myself something nobody had asked me: why did a 2-0 win eliminate the strongest team in the group. The answer lived in data. That 2026 mistake became a fixed marker telling me where I stood.

Years later, sitting in the third row of a martial arts night in Ho Chi Minh City, I met that same feeling again. With one difference: this time there was no recording to listen back to.

Context: three martial arts worlds running in parallel, not talking to each other

Vietnamese martial arts is really three ecosystems, each with a different standard of record-keeping.

The first is traditional martial arts and Vovinam — tied to schools, provincial federations and the SEA Games stage. This is the most tightly organized layer, with a rank system and clear competition rules, yet almost no public database of individual results by bout. Results are published by medal, by event, by delegation. Everyone knows how many Vovinam golds Vietnam won at the home SEA Games 31 in Ha Noi in 2026; almost nobody can trace which opponent a specific athlete beat, with which technique, in which round.

The second is Olympic-style amateur boxing. It has the clearest international standard, governed by the world body and the IOC, with continental qualifiers and public draws. But the number of publicly documented bouts for a Vietnamese boxer in a four-year cycle is tiny. Nguyen Thi Tam competed at Tokyo 2026, the product of a long pathway; yet building a detailed record of every bout she fought before Tokyo means stitching together dozens of scattered sources, many with dead links.

The third is professional Muay Thai and MMA — run by private and semi-professional promotions. This is the most dynamic layer, with the youngest audience, and the least standardized. A fighter can take four bouts in a year under four different organizations, with four different weight-class conventions, and nobody consolidates them into one profile.

Compare that with football. A V.League player finishes a match and within twelve hours has passing data, distance covered, duels won, a heat map and dozens of pages of analysis. A fighter finishes a match and has a vertical clip on social media, a few compliments, a few insults, and one emotional match report.

This is nobody's single fault. It is the result of something concrete: Vietnamese football has a federation with stable revenue, a national professional league, and sponsors large enough to pay an international data provider. Vietnamese martial arts has smaller, more fragmented versions of all of that, and nobody paying for the record-keeping.

Core: when the record sheet does not exist, analysis becomes collective memory

This is where I want to slow down, because it is the root of nearly every other problem.

Vietnamese martial arts does not lack good fighters. It lacks a record system good enough to evaluate good fighters correctly — and that gap is being filled with memory, emotion, and stories nobody can verify.

Take Nguyen Tran Duy Nhat. In Vietnam, almost anyone who follows Muay Thai knows who he is and that he has held international belts from WBC Muay Thai and WMC. Now ask ten longtime fans: which was his hardest fight, which round was he cornered in, which opponent's style troubled him most, and why. Very few can answer in detail. Collective memory keeps the title, not the process. Titles are easy to tell. Process needs data.

The consequences do not stop at media. They reach into how professionals make decisions.

A coach scheduling his athlete needs to know: is the opponent's left hand or right hand stronger, does he habitually eat knees when closing distance, in which round does his conditioning drop. In a martial arts culture with data, those questions are answered by thirty minutes of tape review and a summary sheet. In Vietnam, they are often answered by a phone call to someone who works at the other gym.

That method is not useless. It is often highly effective, because inside information can be more accurate than raw numbers. But it has two fatal limits. First, it does not scale: a coach only has so many contacts. Second, it is unverifiable: when people reconstruct from memory, error appears and nobody knows it did.

The track taught me discipline; the stands taught me to converse with chaos. Both need a fixed point to anchor to. In Vietnamese martial arts, that anchor is missing.

I once listened to an event organizer explain why he does not publish fighter records on his promotion's page: "I'm afraid of being wrong. If I publish and someone nitpicks, I lose more credibility than by not publishing." That answer was honest, and it names the real dynamic. In a system without standards, silence is safer than speaking. But silence accumulates into a large gap, and large gaps always attract someone to fill them — usually with whatever sounds best.

That gap is also where unverifiable legends are born. A fighter can be called "undefeated" for ten years simply because nobody holds a complete list of the bouts he lost. This is unfair to the fighter himself: when results are not recorded, the only thing left is impression, and impression depends on who tells the better story.

Then there is money. What a fighter is paid for a bout depends on who people believe he is. Without a record sheet, that belief is built on follower counts, on viral clips, on a few beautiful moments. Some fighters who fight beautifully but cannot tell their own story earn less than fighters who fight worse but have a better narrative. The Vietnamese martial arts market therefore runs on stories people are willing to believe — exactly as it does everywhere else in the world, except that here we have no tool to check our own beliefs.

One detail stays with me. At a night I attended as a guest, a young fighter won on points after three rounds. The crowd booed, convinced he had been robbed. Nobody in that crowd had a detailed scorecard. Nobody knew how many clean strikes he had landed in round two. The argument ran for two weeks online and ended with nobody changing anyone's mind. That is the price of a martial arts scene without data: every dispute becomes a dispute about belief, and disputes about belief never end.

A big event is never perfect. It is only perfect in the way people choose to remember it. But to choose how to remember, there first has to be something to remember.

Contrarian: do not rush to import a foreign data system

The natural industry reflex at this point is: import the foreign model, build an international-style database, done.

I think that step will fail, for one very specific reason.

Vovinam does not operate on the same frame of reference as boxing or Muay Thai. Scoring, decision criteria, the leg-technique system and the forms, the way beautiful technique is valued — all of that forms its own language. A database designed for boxing has no field to record that a fighter won by controlling distance with leg techniques, or by holding his stance structure for three rounds. Force Vovinam into someone else's data schema and you do not make it more transparent. You make it poorer, and you teach the next generation that only what can be measured with someone else's ruler is worth recording.

Here I want to say plainly what analysts usually avoid: most of the opacity in Vietnamese martial arts is not an accident. It has beneficiaries.

Organizers do not publish for fear of being wrong. Coaches do not publish for fear of exposing tactics. Fighters do not publish for fear of exposing weaknesses. Sponsors do not demand publication because they are buying image, not numbers. Media does not demand it because emotional stories sell better than spreadsheets. None of these people are villains. Added together, they produce a system in which opacity is the equilibrium, and anyone trying to change it takes the risk alone.

And the reverse must be said too, because it is the blind spot of people like me. When I pick up a data sheet and find little in it, my reflex is to conclude there is nothing here worth analyzing. That reflex is wrong. A martial arts culture where everything is measured with one ruler is a flattened one. What makes a fight night in Can Tho or Buon Ma Thuot memorable lives in no data table: the drum, the way the crowd stands at the same instant, an old coach shouting himself hoarse. Those things cannot be measured, and we should not try.

The problem lies elsewhere. A lack of data is a gap to fill. No data at all is an excuse to explain nothing. Those are entirely different, and Vietnamese martial arts sits between them.

I once watched a young coach do what I consider the right first move. He filmed every training session on his phone, named files by date, and reviewed them once a month. No software. No data provider. Just a habit. Two years later he was the only person in his region who could say precisely where his athlete had improved and where he had stalled — and that helped him secure funding for a small event.

That is the most realistic starting point. Not a national system. A notebook.

Takeaway

Vietnamese martial arts does not need a data revolution. It needs a minimum convention anyone can follow: date, opponent, ruleset, result, and one link to video. Five fields. Not beautiful, not synchronized, not sponsored. Just published somewhere another person can find it.

Once those five fields exist, everything else follows. Fans start comparing. Journalists start verifying. Coaches start looking up opponents before accepting. Organizers start noticing that publishing gives more than it costs. And the fighters who fight beautifully but cannot tell a story get a second chance.

Every generation loves martial arts in its own way. Our job is not to force them to love it the way we did. But there is one thing we can hand them without taking anything from anyone: an honest enough record that thirty years from now, when nobody remembers that night, anyone can look it up and know what actually happened on the floor.
