Geronimo made a good point:
...when you actually should be using the broadhead tuning
You can't use paper tuning for broadheads.
Paper tune first, then bareshaft tune, then broadhead tune.
Either of the first two steps can be skipped becauseyou gain precision as you proceed through the steps. If you're not hunting with your bow then you can stop at bareshaft, or go on to fine/micro tuning. If you are hunting, you must end with BH tuning regardless of the other steps you take or skip.
Yimmy, you are already broadhead tuning by comparing the points of impact (POI) of FP arrows, and BH arrows. That's good, but paper can't help you now. You're doing exactly what you need to be doing.
Also, to clear up a bit of confusion, keep in mind that the adjustments for paper tuning vs bareshaft and BH tuning
appear to be opposite because they are measuring opposite things. The paper shows which way the TAIL of the arrow is angledin relation to the point. Bareshaft and BH tuning show which way the POINT of the arrow is angled in relation to the tail. By definition, these two tests will appear to show opposite conditions. Don't get them confused. They really tell you the same thing, but you need to understand what they are saying. You should also know that lots of stuff can mess up paper results making you chase your tail, and paper can also show good flight when you don't actually have it. It's just a rough estimate.
In your case, the arrow is acting stiff (forget the paper results). The arrow is leaving the bow nock-right (and high), and therefore planing (catching the wind and being pushed)to the left (and low)during flight. The difference in POI should increase as you shoot further distances rather than be a constant 5" POI diff all the way out.
The cure is to make the adjustments Geronimo stated (they arequoted directly from the Easton BH tuning chapter, and they have a great foolproof graphic too), or if that does not fix it, get weaker arrows.
Note: The Easton shaft selection charts lean stiff for hunting arrows. Lots of people have hadprobs, and I've learned to shift my selections by one column towards the weaker side.
