ELO
The paired rating a clan carries per Stronghold tier and on the Global Map, where each battle moves points from the loser to the winner.
Also known as elo rating.
ELO is the chess rating, applied to clans. Every clan starts from the same figure, and a battle transfers points between the two sides: beating a clan rated far above you moves a lot, beating one far below moves almost nothing. Losing works the same way in reverse.
It is Wargaming's own number, one per tier, and it is what the game matches clans on. That makes it a measure of results against the field rather than of roster quality: a clan that queues constantly against weak opposition climbs slowly but steadily, and one that only plays a handful of hard battles can sit high on very little.
