Fighting styles
A fighter's style is read from their discipline Elo — separate ratings for striking offense and grappling offense. The lean (striking Elo minus grappling Elo) places them: clear specialists sit far from even, while fighters within 35 points of even are balanced. It updates automatically as results come in, so a fighter who adds a phase to their game shifts over time.
A stand-up specialist who does their damage on the feet — boxing, kicks, knees and distance management. They tend to defend takedowns to keep the bout where their edge is largest, and win by decision on volume or by KO/TKO.
Striking-offense Elo at least 35 points above grappling-offense Elo.
A wrestling- or jiu-jitsu-led fighter who closes distance, scores takedowns and works from top position or the back. They rack up control time and submission threats, and often grind out decisions or finish by submission.
Grappling-offense Elo at least 35 points above striking-offense Elo.
Comfortable in both phases without over-indexing on either — able to strike with strikers and grapple with grapplers, and to dictate where the fight happens. The most adaptable profile, and common among the very best pound-for-pound fighters.
Striking- and grappling-offense Elo within 35 points of each other.
Styles come from the model's discipline-Elo ratings, not reputation — so a fighter known for one phase can read differently if the results say otherwise. The matchup analysis on the modeling page uses the same lean, split at even (no balanced band), to group striker-vs-grappler bouts.
