I have always felt paper tuning was a starting point. From there I always do something to confirm/micro tune. That may be walk back or broadhead tuning for me. I have seen it be near impossible to paper tune high doc arrows at different distances. I think the heavy front ends are flying true and the back of the arrow is whipping or oscillating under the load. I saw this with my 1250 grain arrows with 30% foc. I got the bow set with everything square. Got the best tear in paper I could at 4-5 feet. Then I broadhead tuned. That bow would group broadheads and field points to 50 yes. That works for me.

I haven't made it to 30% yet. I had some at 26%.
I to saw a little more movement on the back of arrow in flight. With that much weight up front the arrow has to load up at first just to get the arrow moving.
I did see better flight when I used the gold tip kenitic 200. I'm sure at 26.5 in shaft the spine was close to 150 to 175. So it was stiff as crap.
I might get them back out. And start light on the tip and load up. And see what happens. With a 150 tip or so this arrow should recover very quickly.
