Pokémon, items, types: the game's tiers (the API stops at C; D is this page's split, mirroring S). Comps are graded stricter, on the pessimistic average (avg + CI) against the reference: S ≤ 3.27, A ≤ 3.92, B ≤ 4.67, C ≤ 5.27, D above. A noisy sample cannot be S. Comps under 30 effective games are hidden by default.
