The FightMetric system is based on qualitative and quantitative research into the things that matter most in ending a fight. Its algorithm is based on historical fight data and guided by the following principles:
The goal of every fighter is to end his fight - Only things that win fights and confer advantages should score points. Those that result in more victories score higher.
Defensive maneuvers can't win fights - If all you’re doing is stopping your opponent’s attacks, you’re losing.
It doesn't matter what you strike with, only where you strike to - Measuring the effectiveness of punches versus kicks versus knees independent of target may be interesting, but gives no indication of fight effectiveness.
Not all strikes are created equal - Power matters a great deal. Even a total head strike count means nothing unless you know how many of those strikes were landed with power.
It's what happens after the takedown that matters - With the exception of slams, takedowns are only valuable insofar as they set up more valuable opportunities on the ground. Taking someone down into guard confers only a modest advantage to the fighter in top position.
Focus on the end result - Little things, like body jabs on the ground, will never end a fight, but they do set-up important things like submissions and guard passes. Remember that the submission attempt or successful guard pass will score the points, and that in their absence, those body jabs were worth little.
Damage is not a one-round effect - Cuts, swelling, and tight joint locks end fights both by doctor’s stoppage and by impairing a fighter’s ability to perform. Those effects last the duration of the fight and should be scored as such, not just in the round in which they occur.
Position matters, how you get there doesn't - It’s unimportant what technique a fighter uses to execute a takedown or a guard pass. All that matters is what position that technique leads to.
Grappling actions have equal opposite reactions - The same number of points granted to one fighter for a position change (e.g., gaining mount) must be awarded to the other fighter should he work his way out of it.
This is fightmetric's FAQ
What exactly does FightMetric measure?
FightMetric produces a comprehensive score that measures a fighter’s total effectiveness in a fight that goes to a decision.
What do you mean by “effectiveness?”
The first principle of the FightMetric system is that the goal of every fighter is to end his or her fight. No one should come into a fight aiming for a decision, so a fight ending is the absolute desired effect. When a fight goes to a decision, neither fighter has produced the desired effect. The question then is, how well did the fighter use techniques that have proven effective in ending fights in the past?
Who cares what happened in past fights, isn’t every fight unique?
Every fight is dynamic, but that doesn’t mean it’s unique. The fact that a particular fighter may have won a fight by flying armbar does not change the fact that flying armbars are not a particularly effective way to end a fight, which is to say, very few fighters have been successful in ending fights with that technique.
What techniques does the FightMetric system track?
Strikes are tracked based on position (striking distance, clinch, ground), target (head, body, legs) and power (power strikes and jabs). Takedowns are tracked by power (regular takedowns and slams). Submissions are tracked in 10 categories that encompass the eight major MMA joint locks and chokes and two categories for miscellaneous locks/cranks and chokes. Guard passes are tracked as improvements both to and from guard, half-guard, side control, mount, and back control. Additional points are awarded for strikes that result in a knockdown and for strikes or submission attempts that cause visible damage. No points are awarded for purely defensive techniques.
How do you decide how much each technique is worth?
The fighters themselves determine the value of specific techniques. Values are tied directly to a database of fight endings. As an example, more fights have ended by kimura over the past few years than in the years preceding them. That being the case, kimuras have become a more effective technique in MMA and the value of kimura attempts has been recalculated accordingly.
Doesn’t this system favor (strikers/wrestlers/submission grapplers) over other styles?
The system favors those that work to end their fights. MMA has proven remarkably equitable to fighters of all styles. Nearly as many fights end by strikes as by submission and the gap between fights ending on the feet versus on the ground is not as wide as most would think. Therefore, the values determined by the historical data provide a level playing field to fighters of all disciplines.
Except for lay-and-pray fighters…
What about fights that end and don’t go to a decision?
