Went out and got my new allegiance today (no pics as of yet, but not bragging about it right now

so man law don't apply) but my question on the tag is it has a listed speed of 311fps on it (IBO) but it is listed as a 29" draw length, so is this speed a theoretical speed based on the 30" draw at 70lbs, or is it a factory speed that was determined by testing this particular bow at a 29" DL at 71 pounds?
Love the bow but a little freaked out because the shop set me up at a 26" draw, due to them suggesting a totally new anchor point, will see how it works out but dang, the new bow might not be the big 'step' up that I was hoping for, great shooter though.
