Current score, fight by fight

Replay of the current-Vertex formula at each completed UFC bout. Hover the chart for the bout that locked in each value.

Current is a live-form rating, so it drifts between fights: recent results age out of the rolling windows and the age curve steps on a birthday — a quiet stretch can nudge it slightly up or down with no bout. The all-time score only moves when a fighter actually competes.
