Thanks for all the information!

I just spoke to West System to find out what they recommend and do in their shop. They recommend maximum vacuum up to 24 inches to make sure all the air is out and control the resin by the size and amount of holes in the bleeder cloth. The technical person went on to tell me of the $40 dollar clip board exercise they do in the boat building school that demonstrated the effectiveness of the types of bleeder cloth.

So what I’ve learned so far seems to be a formula that takes into account the size/type of lay-up, ambient conditions, mix of epoxy, amount of vacuum, and the size of the bleeder holes.
