The daily limit
75 pitches at nine and ten, 85 at eleven and twelve
Those are the published daily maximums, and the rest schedule that goes with them is the part people skip. 1 to 20 pitches needs no rest day. 21 to 35 needs one. 36 to 50 needs two. 51 to 65 needs three. Anything above that needs four. Nobody pitches three days in a row at any count, and a pitcher who has come off the mound does not go back to it later in the same game.
