NOT to stir the pot, but who else noticed that velocity went up faster below 350 gns?
How many arrows were tested below 350gns? below 400gns?
This means on this bow once you get below 350gns, the KE losses would either reduce, or REVERSE!
Again, the KE measurements for the first chart were done with one bow. As has been mentioned, some bows work better with certain set-ups. (i.e. long bow and heavy arrows, VS cam bow and light ones. long bow doesn't work well shooting light, cam bow does).
The ONLY issues he addressed, was KE vs. Momentum...NOT velocity. It can be argued that velocity DOES play a part if you believe KE is more important than momentum. as momentum is weight times velocity, and KE is weight times velocity squared (then adjusted by a number to give relevant measurments

Here is a chart from another test on the same subject....notice penetration went UP with the faster arrow with less KE.
NOT by much...more importantly, it DID NOT DROPwith lighter arrows and LESS KE.
If anyone wants the rest of the article posted, lemme know. Otherwise I'll save the energy (sorry...bad pun )

This all said, I WILL agree that KE is the MAJOR factor in penetration......but not the only. Velocity MUST be added to the equasion.
