Yep, thats where I have been working off offor years and years, but it doesn't asnwer my question. But what I am asking aussie is broadhead tuning more precise than bare shaft? Do you know the answer. Easton does not say.

But don't worry, I made an adjustment of 1/4" on nocking position and now I am hitting the same as thunderheads. And it seems to be flying better with field points. Just hopeing some on of you tuning guys could confirm I what I am see sounds right.
