And with regards to running slightly different pressures on one side or another to compensate for a track that has substantially more turns one way, that is also very common. A lot of people will even their tire pressures out right when they come off the track hot, which effectively offsets them to compensate for one side or tire being worked more than the other(s).
And just to echo what was said by many, I would NEVER induce a stagger condition by increasing tire pressure.
