Percentiles compare the same position using domestic games in the selected benchmark. A season compares that year; All seasons compares each player’s career averages across their available years. Higher means more of that metric, not an overall player rating. Career averages are not adjusted for changes in patches, game pace or formats. All Tier 1 circuits is available when the player has recorded Tier 1 domestic games in this position and selected period.

Each player needs at least 20 games, 20 valid observations and 80% metric coverage. Each benchmark needs at least 5 qualifying players within a circuit or 20 across Tier 1 circuits. GD15 ranks players with sufficient recorded data and identifies missing leagues. Other metrics also require 80% coverage of sample-eligible peers. Percentiles use the midpoint of tied positions; a fully tied group is 50. Absolute ranks start at 1 and ties share the same position. Missing values stay unavailable. Changing the benchmark also changes the games used for the player’s actual values.
