c903,you are totally missing the point.

There is a forgiveness factor that goes along with this whole thing.If a BOW AND ARROW AND SHOOTER is tuned properly then it doesn' t matter if the arrow is carrying a broadhead or a field point.It will be more forgiving to a less than perfect shot.The arrows will hit VERY close to the same point.As I stated earlier,my broadheads hit the same and I didn' t tune the broadheads in at all.NEVER made an adjustment.This was a setup that I used for competition and was setup for the most accurate flight and most forgiving that I could possibly have(I did change from glue in points to screw in and from 1.75 vanes to 3" ).The vanes had a very slight offset.IF it is right on then they will be close.FOR THE MOST PART.There are some bows and broadheads that just don' t want to come in.Most of those cases can be fixed also but there is a line that we sometimes cross as to what is really necessary.
