lilhunter,

I don't have a perfect answer for you.

But, in one of my earlier posts I mentioned a situation that occurred this post bow season.

Laser rangefinder....a doe in the spot that I ranged with that laser rangefinder.....I practice on weekly basis..year round....

..and I still missed.

In my opinion, it stops becoming hunting and starts becoming shooting when the archer can't miss.....when there is no chance of human error.

Hope that is what you are looking for.
