Vitals, record, nickname and camp come from the public UFC fighter register and are current, not a snapshot of fight night. UFC bouts, finish rate and every storyline line are counted off the official UFC fight record. A tick marks the side holding the raw edge in that row — longer reach, taller, younger, more bouts, a higher finish rate. It is a fact about the tape, not a prediction, and rows with no clean comparison (record, stance, gym, hometown) carry no tick at all. Any row we cannot fill on both sides is left out rather than half-drawn. Streaks, bout counts and finish rates are as they stood going into this fight — this bout and everything after it is excluded from the count.

Significant strikes, takedowns, control time, knockdowns and submission attempts exactly as UFCStats recorded them for this bout, round by round. Zone percentages are that round’s landed head, body and leg counts over their own total — raw arithmetic, nothing modelled or smoothed. A round in which a fighter landed nothing shades empty and reads zero; it is never filled in from the round before.

Official cards come from the UFCStats fight record and MMA Decisions. Media cards and the fan vote are MMA Decisions’ own collection and are not official. Judge tendency figures are that judge’s whole recorded history, not this bout — they are context for how a card was scored, never a claim that it was scored wrongly.

What the price did in the week before the cage door shut, with the moment our pick was frozen marked on it. Where we captured no price history for a bout, this panel will say so rather than draw a line that was never there.
