When the Scorecard Is Blank: Taolu, Sanda and Combat Sports Run on Three Different Logics

It was 2:47 a.m. in Seoul and a few shop signs were still lit outside the window. A data file had just landed on my workstation: title field blank, source field blank, article-type field blank. At the top of the file there was a single label, martial_arts, and the information list underneath it held nothing at all. Anyone who works in officiating has one reflex when a field is empty: fill it in. I have done exactly that across nine years of watching this industry. That night I left it alone and typed four words into the notes box: not yet determinable. The correct state here is undetermined, not neutral — and between those two ideas sits a whole profession. Two scorecards were on my desk. One came from a three-round bout under the unified rules, marked 10–9 in the opening round. The other came from a form routine, marked with three columns — A, B and C — plus a separate box for difficulty value. Both cards use the word “score” and share nothing else. That is why the empty file could not be repaired by looking up a few more numbers. I learned to read rules on a June night in 2026 in Kazan. In the second minute of stoppage time in the South Korea–Germany match, Kim Young-gwon put the ball in the net, the assistant referee raised the flag for offside, VAR intervened, and the goal stood. According to FIFA records and the reporting of that period, it was the first goal in World Cup history awarded after a video review. I was seventeen. I did not celebrate with my friends; I pulled down all 64 matches and built a 47-page diary about VAR alone: minute, score, referee position, number of monitor reviews, minutes of added time. Kazan erased a goal, but it opened an eye. The 2026 season had no crowd, but it had a very large ear, and I sat inside that silence to encode 1,247 referee decisions drawn from the 2026 World Cup and three K League 1 seasons. One result stayed in my drawer: after a team suffered a wrong decision, its chance of receiving a soft penalty inside the next two matches came out at roughly 89 percent. I wrote 30 pages and built the tables over four months, then never sent it, afraid that one statistic was missing. That is how a systematic perfectionist procrastinates, and it is not a virtue. It took the 2026 World Cup in Qatar for me to see that my error sat somewhere else. I used the compensation model to predict that referees would limit cards in the group stage to protect the flow of matches. It was right in 26 of 36 matches, then collapsed in a group game where my card count was completely wrong. After the tournament I spent three weeks interviewing two former FIFA referees, and they taught me to read a referee’s body language when the stands push down on him. The variable I was missing was not in the spreadsheet. The larger missing variable was a name: I had been calling everything on the mat “martial arts” and analysing it as though only one rulebook existed. That is where the empty file becomes worth reading. The martial_arts label folds at least three competition systems into one word, when those three systems do not share a unit of measurement. In modern combat sports, the unit is the round and the scorer is a judge seated away from the mat. In MMA, the criteria revised by the Association of Boxing Commissions in 2026 put effective striking and effective grappling first, ahead of aggression and cage control — meaning a round is judged by the damage inflicted, not by a countable number of strikes. Professional boxing uses the 10-point must system, where the round winner takes 10 and the loser takes 9 or 8. Both systems produce a binary outcome once rounds are added, and that is why they can carry a probability model. In sanda, the unit is still the round but the logic is different: points accrue for valid strike types, for knockdowns and for forcing an opponent off the platform, minus deductions for fouls. Viewers raised on MMA routinely mistake sanda for “MMA without ground work,” when sanda has its own platform, its own foul table and its own way of separating a winner from a loser. In taolu, the unit is stranger still: a single routine, usually running around one minute twenty seconds depending on the form. As I understand the current regulations of the International Wushu Federation, the judging panel is split into groups: Group A scores movement quality, Group B scores overall performance, Group C scores difficulty. An athlete’s difficulty list is registered before competition, the way gymnastics routines declare a start value. The highest and lowest panel scores are typically dropped before the average is taken. From what I have observed at regional events, the pool of qualified taolu judges is always thinner than the pool of officials needed for a night of fighting, and assignments are usually fixed a week in advance. Those three systems produce three outcomes that cannot be converted into one another: a winner, a cumulative strike total, a decimal. A single headline can process all three with one verb — “won” — and that verb is where the framework error begins. My work is to stand at the edge of those three systems and measure the gap between an event and the way it is retold. I don’t watch the goal; I watch the camera that watches the goal. In MMA, after a decision the broadcast cuts to the judges’ table and the audience sees the people who just scored the fight. In taolu, the panel sits at the edge of the mat, heads down over the sheets, and almost never enters the broadcast frame. One discipline, two presentation regimes, and the result is two different levels of trust in the audience’s mind — not because taolu judges are less transparent, but because the camera was never placed there. Raheem Sterling went down inside the box in the Euro 2026 semi-final at Wembley, referee Danny Makkelie awarded England a penalty, and the argument around that moment ran for years. Most of that argument was about feeling rather than law. Which angle aired, how many frames of slow motion, where the cut landed — all of it is an editorial decision before it becomes a public decision. That gap flows downstream along a fairly clear path. A decimal result cannot feed a betting market, because there are no two sides to take. No betting market means no data company paying for a live scoring feed. No live feed means no automated highlight packages for platforms. No highlight packages means less broadcast time, less sponsorship, and fewer trained officials. Run that loop long enough and it pushes a country’s best athletes toward the sport with a binary outcome, regardless of which sport they are actually better at. Based on my experience following matches and championship events, the heaviest damage lands not on the audience but on the description. A routine that loses 9.68 to 9.71 is written up as a “comprehensive defeat,” when the 0.03 gap usually comes from a 0.1 deduction for a hand touching the mat or one unfinished difficulty movement. The reverse error is identical in kind: a 10–8 MMA round gets described in the language of gymnastics, “dry scoring, no emotion.” Both directions are framework errors, and both have a price: they misprice an athlete’s career, misdirect a sponsor’s expectations, and corrupt the data of the sport itself. This is where I have to argue against my own industry’s habit. The common reflex when a file is empty is to demand more data: more cameras, more metrics, more tables. But the blank box in that file was a classification box, not a number box. A thousand new numbers inside a wrong frame still produce a wrong conclusion, only a more credible-looking one. Data never fouls; the writer is the one who gets the card. There is also a reverse prejudice I once held and had to drop: that taolu judging is subjective and therefore less serious than round-by-round scoring. Look closely at how it operates and the picture changes. Pre-registering the difficulty list turns the hardest part of a routine into a public commitment, and dropping the highest and lowest scores trims the influence of one extreme judge. A 10–9 round has no equivalent mechanism: nobody drops an outlier judge, and nobody declares in advance which criterion will be favoured for which fighter. The law is the only thing that never steps into stoppage time, but the application of the law always does. Undetermined never stays still. It gets filled, and what fills it is usually the loudest story in the room: the rivalry story, the robbery story, the story of a star stripped of what belonged to him. An empty file does not generate a wrong conclusion by itself, but it leaves a space where a wrong conclusion is always ready to live. The real danger is not a file left blank. It is a file filled with numbers taken from another discipline’s scoring frame. From tonight, every combat-sports analysis should carry a rules label, the way a box carries a nutrition label: which sport, which scoring unit, who scores, and who holds the right of appeal. A label like that costs one line, but it forces the writer to choose a framework before choosing a conclusion. And the test sits somewhere else: if audiences read the rules label before they read the result, would half of the arguments online still have anywhere to live?
