Answers.Text: Small comment: For sound stats and a scientific article  :-), you also would have to check (no pun intended) each and any promotion whether it was a "nonsense" promotion. If it was nonsense, maybe the player was in time trouble and quickly hammered a rook on the board (not anyone knows you may stop the clock to order a second queen from the referee).

Answers.Text: Just a small note, some games where a pawn that's about to (most likely) promote to a queen were resigned before a promotion happened, so maybe there were some more games where if it were to be played on, more promotions to either piece would've happened.
