Paul.

You saved me a lot of typing.

One thing you guys must also take into concideration is that KE is measured a couple of feet in front of the bow.

What I want to know is what is my arrow doing at 20,30,40 yards etc.

I did do a lot of testing a few years ago with light, heavy arrows as well aslow FOC and Extreme FOC.

Unfortunately I had a computer crash and lost all my data and I dont really want to kill another crono at 50 yards like I did the last time
