The judo stats worth tracking are few: win rate, ippon ratio, golden score record, scoring techniques and attacking side. Tracked over twenty or so fights, they show what memory distorts. Read badly, they send you to work on the wrong thing.
Why track judo stats at all
A competitor's memory is a poor judge. You remember the clean ippon with seoi-nage (shoulder throw) and the unfair loss in the final. You forget the three fights lost to the same stepping-out penalty.
For many competitors, the gap between what they believe and what the numbers say is almost always the same. They overrate their standing game and underrate what happens on the ground. One season in a table is enough to see it.
The five judo stats to track
| Stat | How to calculate it | What it reveals |
|---|---|---|
| Win rate | Wins / fights | Overall level, compared by competition level |
| Ippon ratio | Wins by ippon / wins | Ability to finish |
| Golden score record | Wins / fights that went to extra time | Conditioning, nerve, penalty management |
| Scoring techniques | Scores per technique | Your real weapons, not your favorite ones |
| Attacking side | Scores on the right / on the left | How readable your judo is |
Win rate
Everyone looks at this number, and it lies the most. A 70% win rate at local events is not worth a 40% rate at national level. Always split it by competition level. Otherwise you will conclude that you are getting worse in the very year you move up.
Ippon ratio
A judoka who wins a lot but rarely by ippon lives dangerously. They win on waza-ari or on penalties, so their fights stay open until the last second. A low ratio is not a flaw in itself. It is a signal to work on finishing: follow up on the ground after a waza-ari, or look for the second attack.
Golden score record
Golden score is a test of its own. Some athletes lose it almost every time. The usual causes, from most to least common: lack of gas, a penalty picked up through tension, fear of attacking.
A poor extra-time record is fixed in training with randori at equal score, restarting the moment someone gets an advantage.
Scoring techniques
Write down the technique behind every score, yours and the ones you concede. Your list of scoring throws is often shorter than you think. Many competitors have two techniques that score and five they are "working on". That helps you decide what to keep in your uchi-komi sessions.
On the conceding side, repetition says even more. Three losses to o-uchi-gari (major inner reap) in a season point to a posture problem, not bad luck.
Attacking side
A right-hander who scores 90% of the time to the right is easy to read. Regular opponents know it. Adding a left-side attack, even a rare one, changes how opponents react and opens up the strong side.
Common reading mistakes
Too few fights. With eight fights, one result moves the win rate by more than ten points. Wait for a wider base before drawing conclusions.
Mixing sports. An athlete who does both judo and Brazilian jiu-jitsu must keep separate stats. The ways to win are not comparable, and a blended rate would mean nothing.
Ignoring context. A green belt losing to an experienced black belt is not the same as losing to a beginner. An "opponent level" column fixes that.
A worked example
Take a fictional junior competitor with 24 fights in a season. He wins 14, four of them by ippon. He goes to golden score six times and loses five. Nearly all his scores come from ko-uchi-gari (minor inner reap) and seoi-nage, all to the right.
Quick reading: the win rate is decent. The ippon ratio is low and golden score is a black hole. His judo is readable, with one side and two techniques. The season plan almost writes itself: ground follow-ups after waza-ari, randori in extra-time conditions, and one left-side attack to build.
How to collect the data
A paper notebook works if you write things down the same day. An app like Jutrack lets you log a fight in under thirty seconds (score, technique, opponent) and calculates win rate, ippon ratio and golden score record without a spreadsheet. The tool matters less than doing it every time.
For fight-by-fight review, our guide on how to analyze your judo fights gives a method. To track training as well, see the judo training journal.
How to use your stats with a coach
At the start of a season, sit down with your coach and look at three numbers only: ippon ratio, golden score record and the list of techniques you conceded. Pick one measurable goal for the season. For example, "win half of my golden scores" rather than "get stronger". A measurable goal can be trained. A vague one only gets talked about.
These numbers make most sense when you aim at a specific step in the judo competition levels. Start with last season, even from memory, before you plan the next one.
