Re: PCI Size
First, Difficulty is the most noticeable factor since you can change it mid-game and see the size change.
To understand this, you need to understand how a batter and pitcher's ratings play off of one another. Contact does have an effect, but it's also weighed against the pitcher's H/9 attribute. Same for Plate Vision (which also has an effect by itself), being weighed against a pitcher's K/9. Power seems to have a small PCI effect (its main purpose is determining how hard a solid hit inside the PCI is, of course), but unless something's changed in the last few years its opposing rating HR/9 only affects simmed games and not played ones. Those ratings all come together on each at bat to determine the hitter's PCI. The PCI size itself is simply an approximation of the current hitter's overall ability vs the current pitcher.
Discipline doesn't really have any effect on PCI (its stated effect is that it is a factor on checked swings and increased walks), and I'm still not really sure if that and its opposing rating, BB/9 (a pitcher's general accuracy stat), interact at all.
Just as a quick test, you can take any MLB ace and throw him against a Double-A team - you should see significantly smaller PCI's that you'll see in MLB-only games, assuming the difficulty level is the same. That's not only because of AA's lowered contact - it's a double-whammy against the batters because they're facing a top-level pitcher. If you started a normal AA pitcher, you'd see the PCI's look a lot more normal-sized, generally.
I tested all this out by checking the same matchup over repeatedly with different ratings tweaked up/down. I can show the screenshots if you like to prove what I said above is true. Most of this I already knew from past posts by Brian Ma, I was just re-confirming it.
