Calibrating any season where the two leagues play under different rules is challenging.

And you are correct that monkeying with the pinch hitting settings will change other numbers ... as should be the case. As it is, if the lack of CG in the NL coincides with a reduced number of AB for all pitchers (and it's hard to imagine otherwise), then your seemingly "correct" numbers for that league are masking a slightly (or perhaps significant) diminished offensive output. The magnitude of this can only be determined by how many extra AB position players are receiving, but one would expect that position players should significantly outhit pitchers, therefore (all other things being equal) if pitchers aren't getting the proper number of AB, then your offense in the NL should be inflated accordingly. If it isn't, then the NL numbers aren't really "correct" at all.

You'll also likely have to go to the team level (if you haven't already) to get things to work out correctly. In 1990, the Dodgers led the NL with 29 CG. By contrast, the Cardinals only had 8. The durability settings of their starters will take care of this to some degree, but there's a definite difference there in the way that Lasorda viewed and used pinch hitters/his bullpen vs. the Cardinals trio of Herzog, Schoendienst and Torre. And you'll need to go to the team level to model that.

It just depends on how much work you really want to do, and where your definition of "accuracy" lies.
