The tightest PWHL race charted came in 2025-26: the Montréal Victoire over the Boston Fleet on winning percentage. Below, every race charted since 2024, ranked three ways: by final margin, by lead changes, and by days spent within three points. How each list is computed is spelled out under the lists.

Everything on this page comes from the same season files the charts draw, with standings read as each day ended. All 3 charted PWHL races from 3 finished seasons enter: every race from 2024 to 2025-26. Wild card races are not ranked; their story is the playoff cutoff, not first place.
Tightest finishes ranks races by the final gap between first and second place, in points. Ties are broken by how late the winner took first place for good, then by lead changes, then oldest first. Two teams the standings cannot separate are shown as level, with no winner named; where the league settled such a race another way, the linked race page tells that story. A margin of zero with a winner named means the race was decided on winning percentage.
Most lead changes counts a change only when a new team passes the leader outright. A day spent tied on top stays with the team already leading, so a tie can never inflate the count.
Most days within three points counts the days on which this race's teams played and the top two ended the day within three points of each other, the most a single result can make up. Days a league stood idle (a strike, a pause) are not counted: a frozen gap says nothing about a race.
Only finished seasons are ranked. Seasons shortened by strikes or other stoppages count as played; every irregularity in the record is listed in the data notes.
