I can't say for all Manufactures, but My proshop tells me that he has talked with bowtect and they recomend (peak weight) that the limbs be bottemd out. I have always hunted with my limps bottomed out backked off a quater turn. That is just they way the old style of bows were. I have specificlyy asked the pro if my warrenty covered cracked limbs if the limbs are bottomed out, I specifically him if the warrenty covered it because these are only 70lb limbs, I asked him how the bow would hold up with the limbs bottomed out, I also asked him if by bowtech standards if this was what bowtech considered peak weight or if they considered 70lbs peak weight since the limbs are 70lbs.

His response is after talking with bowtech is that peak weight is the limbs bottomed out, they will cover anything that happens to the limbs on the bow. So I shoot my bow maxed out at 74lbs.
