Life is Good. 


Lets say I estimate the bow is storing 93% of draw force. So it would be 93% X draw weight ( 98# ) That would give me 91# of stored energy. So now I simply add enough imaginary weight to the arrow that we know the speed of which is 256 fps to give me 100% efficincy. On the icase if I add 160 grains to the 463 grain arrow and then check the ke at 256 fps it will give me about 91 Ft#.
