If you do not know how many times a pitcher uses his 1st pitch vs his 2nd or 3rd, then what is the value of having a rating for the 1st pitch, 2nd pitch etc? If the game is not simmed on a pitch-by-pitch basis, then how is it simmed? Then why does a catcher's pitch calling matter?
It is simmed on a PA-by-PA basis.
Th catcher's PC impacts the effectiveness of the pitcher.
*How* it does so is unclear, and has been explained in contradictory ways by CS/Dev Chats. The two main theories out there at the moment (among those who think it matters, since there are also those who think it is worthless) are:
1) PC helps pitchers equally, essentially acting to depress OAV.
2) PC boosts the effectiveness of a particular pitcher's pitches, perhaps by making the engine place greater weight in its calculations on the P#1 and/pr the highest rated pitch.
