Concentrated: Meganium alone carries 49.51% of the 2,056 teams running Overgrow, and its top three species together account for 83.56%.

The 45.73% figure is a posterior mean, not a raw average; the interval behind it is 45.18%–46.28%, from 20,732 games. That is a narrow band for a figure with this many games behind it.

Tournament decklists and real match records for Pokémon Champions, ingested from Limitless, Victory Road and the official circuit. These figures are all-time over the whole corpus, not scoped to a format or window the way the boards above the search bar are. Win rates are shrunk toward the field average rather than printed raw, so a thin sample cannot top a board.
