I don' t think I worded my question very well. I wasn' t really concerned with accuracy. I was trying to find out if the tuning was considered good, even if broadheads grouped 6" away from the grouping from the same arrow with the same weight field tips. I have always found that if, in addition to fine tuning, I tweak for the ideal draw weight for the arrow spine, I get groups with either broadheads or field tips, that are very close to each other. That is, as long as everything else is the same (same fletching, same length, same arrow weight).

In other words, if my grouping for broadheads was 6" away from my grouping with field tips, I would take that to mean that something was off with my tuning, my draw weight, or my actual arrows. I doubt that I' ve ever tuned a bow that had the broadhead groups more then 2" away from the same arrow with field tips. In fact, I would bet that they' re usually within an inch at 20 yards.
