Thanks guys,
3 weeks out from a meet, I have to be a
PR machine every week until then!
For the boards we use phone books(yellow pages), not sure how thick they are, maybe 3 inches? I'm not good with guessing like that. 3 board(3 books) for me ends up being a bit less than half of my usual ROM since I have long arms, and 2 books is probably about 2/3 of normal ROM bench press, but done close grip.
I think it's impossible to get a bench shirt on without help lol! I can get into my suit though, suit slippers make that much easier.
