Thrown strikes per minute
ⓘ

Unlike traditional systems, "Stats Fight" doesn't aim to count every movement - it focuses on meaningful, fight-relevant actions. What Counts as a Thrown Strike? In "Stats Fight", not every hand movement is recorded as a strike. A strike is only counted if it: poses real danger to the opponent is thrown with intent to impact, not just to measure distance This means: feints are excluded probing the distance are excluded 👉 The goal is to filter out “noise” and focus only on actions that could realistically influence the fight.

Landed strikes per minute
ⓘ

What Counts as a Landed Strike? The core principle is damage and impact. A landed strike must be: a high-amplitude action (not a light touch) either cleanly reaching the opponent or meaningfully interacting with a solid “frame” block pressed against the body or head 👉 Accuracy alone is not enough - the strike must carry visible intent and effect.

What as a successful takedown? In "Stats Fight", a takedown is considered successful only when it achieves real impact - either the fighter deals damage or establishes control over the opponent after the takedown. It’s not just about bringing someone to the ground, but making that action meaningful in the context of the fight.

Stats Fight Rating - Fighting Level

Stats Fight Rating (Fighting Level) is a universal measure of an MMA fighter’s strength and skills, developed by the Stats Fight team. Each fighter is assigned a score from 0 to 100 that reflects their overall effectiveness. The score is based on six key attributes. 1. Power: An assessment of offensive power and the ability to finish a fight by knockout or submission. 2. Speed: The intensity, frequency, and pace of striking. 3. Takedowns: The effectiveness of wrestling techniques and bringing an opponent to the ground. 4. Defense: The ability to avoid damage, block strikes, and defend against takedowns. 5. Control: The ability to dominate in the clinch and keep an opponent grounded. 6. Experience / Opposition: The level of competition the fighter has faced throughout their career.
