By game length

This is what happened, not a recipe: game length is an outcome of the game (games decided early are short).

No clear difference by game length.

How it's calculated

  • Ranked random-map games from the current patch, without mirrors or games under 5 in-game minutes.
  • First the players' Elo difference is removed, so what's left comes from the civs: chances are at equal Elo.
  • A model adds up the strength of each civ and each matchup by map, Elo band and length; whatever has few games stays close to the overall number, so a cell with 4 games doesn't make things up.
  • The range is where 90% of the likely values fall. It's even if it touches 50%, and for game length something is only claimed if the shortest and longest bands don't touch.
  • Length is in minutes of the game's clock.
