How many Bowman base cards in a hobby pack? HTA?

[jswaykos]

I enjoy putting together cheapy sets, and I've always liked Bowman, but the newer stuff confuses me with eight hundred different sets in each pack. In ONE pack of 2009 Bowman (regular, not DPP), how many BASE CARDS ONLY would I get? What about a jumbo pack?

Has anyone collated the base set? If so, how many boxes did it take? Need something to pass the time until 2010 Topps is released...
