That’s a pretty fast bow Kenny. Good job!
The only explanation IMO, is that when anyone shoots with fingers they are pulling back further when they release, especially through a chrono. We are, after all, wanting a bigger number.
I know that for me, on longer shots, I subconsciously pull North of my normal draw length compared to shooting groups at a 15-20yd target.
All things being EXACTLY the same draw length, it’s physically impossible for fingers to be faster than a release
