Honestly, for me it is a waste of time. I've made a dedicated effort a couple times to keep an open mind and try it and I end up WAY underspined for hunting arrows. Maybe things change when I put a big Snuffer up front or the 4 X 5 1/2 inch high profile feathers on, maybe I release strangely, I don't know, but it just doesn't predict a good hunting arrow for me.
I guess I'm bullheaded about some things in my hunting arrows - 1. I know what broadhead I'm going to use so changing point weight is not feasible and 2. I use big feathers - cheapest insurance you can get for a mistake under duress and 3. I refuse to shoot an arrow that sticks 2 inches off the front of the shelf - I cut my arrows 1/2 inch past the shelf so changing arrow length is not an option.
I do have plenty of aluminum arrow sizes, though, and even changing field point weight with those hasn't gotten me to an arrow that bareshafts acceptably that I can use for hunting - always weak spined.
So I'll just keep working up my arrows with feathers on, what flies good to "my eye" with a broadhead.
Oh yeah, and I guarantee I'll continue to shoot completely through animals with my moderate weight, non-bareshaft tuned arrows with inefficient, non-single beveled big broadheads!
Never bareshafted for 25+ years and all went well, so I figure it will work for me for at least another few decades.
