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.

Macy Chiasson

1.87takedowns / 15 min

Career UFC takedown rates exactly as UFCStats publishes them: takedowns landed per 15 minutes, completion rate, submission attempts per 15 minutes, and the share of takedowns tried on them that they stuffed. Attempts per 15 is the one derived figure — landed ÷ completion rate — and it is omitted wherever either input is missing. UFCStats writes 0% where no attempt was recorded at all, so a percentage of exactly zero reads “n/a” here rather than as a measured rate. “Field” is the average fighter in that weight class, or across every division where a class is too small to average. Rate bars run to the population’s 95th percentile (5.00 takedowns / 15m); a fighter above it pins the bar. Percentages are drawn on their own axis.

OpenClosing consensus (BFO, vig removed)

Ailin Perez opened at 54.1% and closed at 62.5% (+8.4pp), with Macy Chiasson moving the other way by the same amount — the two are one de-vigged pair, so they always sum to 100%. There is no line between those two points because nobody recorded one: we hold the open and the close for this bout, not the days in between.

Our published call had Ailin Perez at 61.2%. At the closing consensus, the de-vigged market had him at 62.5% — our number sat 1.3pp below the market’s. Two numbers, side by side. How our calls have actually done is the public record, not one bout.
