Close Fights, Quantified: Building a ‘Robbery Index’ from Strike/Takedown/Knockdown Data
Remember watching Paddy Pimblett get his hand raised against Jared Gordon and feeling like you’d just seen a ghost? The commentators were stunned, social media erupted, and thousands of fans all screamed the same word: “Robbery!” It’s a feeling every fight fan knows by heart—the raw injustice of a baffling decision that seems to defy everything you just saw. You’re left staring at the screen, wondering how the three people judging cage-side saw a completely different fight. That feeling of disbelief is the most frustrating part of MMA. For years, the debate over controversial decisions has been a war of opinions, fueled by passion but rarely grounded in fact. But what if we could move beyond feeling? What if we could actually measure a robbery, using the same numbers the UFC tracks for every single fight? This question is at the heart of our UFC controversial decisions analysis. To answer it, we decided to stop shouting at the TV and build a ‘Robbery Index.’ We created a ‘computer judge’ and trained it on the statistics from thousands of fights with clear outcomes. By analyzing everything from knockdowns to takedowns, our system learned how much each action contributes to a victory, effectively building a predictive MMA model without human bias. This Robbery Index pulls back the curtain on MMA judging by breaking down the simple building blocks of a fight—powerful strikes, dominant takedowns, and game-changing knockdowns—to explain how a data-driven judge values each one. We’ll then unleash it on some of the most debated fights in history, from Jon Jones vs. Dominick Reyes to Georges St-Pierre vs. Johny Hendricks. Our goal isn’t to replace the judges, but to give you, the fan, a powerful new tool. By the end, you won’t just feel a decision was wrong—you’ll understand the numbers behind that feeling and have the data to make your case. Why a “Close Round” and a “Dominant Round” Can Get the Exact Same Score Ever watched a fight where one fighter gets clearly battered in a round, only to get their hand raised at the end, leaving you yelling at the TV? The reason often comes down to MMA’s strange and sometimes frustrating scoring method: the “10-Point Must System.” Think of each round as its own mini-fight with a simple report card. The winner of the round gets 10 points, and the loser gets 9. This is where the controversy begins. The system doesn’t care how much you won the round by. A round won by a single, glancing jab in the final seconds is scored 10-9, the exact same score as a round where one fighter decisively landed the harder, cleaner shots from bell to bell. This creates a scenario that fans find maddening. Imagine Fighter A narrowly wins the first two rounds. They were slightly busier, maybe landed a few more jabs. The score is 10-9 for him in both rounds. But in the third round, Fighter B comes alive and completely dominates him, landing heavy shots and nearly getting a finish. Fighter B clearly wins that round, 10-9. When the scorecards are read, Fighter A wins the fight 29-28, even though the most memorable and damaging moments belonged to his opponent. Because of this, looking at the total stats for a 15-minute fight can be a trap. A fighter can land fewer total strikes and even take more damage overall, but if they convinced the judges they won two out of three rounds—no matter how narrowly—they walk away the winner. This forces us to ask a more important question: what are the judges actually looking for to decide who gets that “10”? It all starts with the idea of “significant strikes.” What “Significant Strikes” Really Mean (And Why They’re Not All Equal) When you see the stats pop up on screen after a fight, your eyes are probably drawn to two numbers: “Total Strikes” and “Significant Strikes.” For understanding who really won, you can almost completely ignore the first one. Total strikes count everything, including weak jabs that are just meant to test distance or pitter-patter shots on the ground with no power. Significant strikes, however, are the ones that count: power shots thrown with the intention of doing damage. Think of them as strikes thrown at a distance or powerful shots from the clinch or ground. They are the primary tool commentators and judges use to measure who is winning the fight. This distinction is crucial because the official judging criteria prioritize effective damage above all else. Significant strikes are the clearest and most objective evidence of that damage. If Fighter A lands 50 significant strikes to Fighter B’s 25, the simple story is that Fighter A inflicted twice as much damage and should win the round. Our Robbery Index, therefore, uses significant strikes as its foundational building block for determining who is winning the striking exchanges. But here’s a secret that the official stat sheet doesn’t tell you: not all significant strikes are created equal in the eyes of a judge. A booming head kick that snaps a fighter’s head back is counted as just one significant strike, the same as a single, hard leg kick. The visual impact of a strike often matters more than the raw number. One punch that visibly stuns an opponent can outweigh the value of five other “significant” shots that were absorbed without reaction. This is where judging becomes subjective and controversial. Ultimately, while counting significant strikes gives us a far better picture of the action than total strikes, it’s still an imperfect measure of a round. The story the numbers tell can get even more complicated when one fighter changes the entire landscape of the round with a single, powerful move that isn’t a strike at all. The Takedown’s True Value: How 5 Seconds Can Steal a 5-Minute Round That single, powerful move that can flip a round on its head is the takedown. In the simplest terms, a takedown is when one fighter takes the
