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.

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.

(+) Positive factors: impactful strikes, knockdowns, successful takedowns, mat control, and submission attempts.
(−) Negative factors: low striking accuracy, poor takedown defense, passivity, and losing the fight itself.
