Every rated player-season in the archive, ranked -- not one draft, not one squad. A count (runs, wickets) carries no volume floor; a rate (strike rate, economy) is floored at the same ball counts the draft's own rating gate uses, so a two-over spell can't win an economy title.
By the card's own 70-99 rating -- batting and bowling already blended into one number where a player did both.
The archive's own extremes -- one board per measure, twenty seasons deep.
