Average tier
The battle-weighted average of the tiers a player has played, used to put their raw averages in context.
Also known as avg tier.
Average tier weights each vehicle's tier by the battles played in it. An account that has 10,000 battles at Tier X and 200 at Tier II sits just under X, not somewhere in the middle.
It exists to make raw averages readable. Damage, credits and experience all scale steeply with tier, so two accounts with the same damage per game and two tiers between them are not comparable at all. WN7 used it as an explicit correction term, and per-vehicle ratings replaced it by measuring against each vehicle instead.
