The Opponent Win Percentage Metric (opWPM) reflects the strength of a team's opponents during preliminary rounds. The opponent's prelim win percentage is the total number of an opponent's prelim wins divided by the number of prelim rounds. Used by Tabroom, teams with similar win-loss records will have comparable opWPM scores, though slight variations can occur due to pre-matched rounds. The metric ranges from 0 to 1.00.
