It's not only about peak weight, but the area under the draw force curve. Bows designed for speed take advantage of more stored energy with harsher draw curves (harder cams).

If you have a 500gr, 230fps coming out of both a 60# and 70# bow, obviously the 60# bow will have a harsher draw force curve than the 70# bow. The 60# (with hard cams) will have more severe curves to store the same energy at full draw as the 70# bow (with round wheels). The area under the curve is proportional to the stored energy when the bow is drawn.
