just because you use the fletching to touch your nose at anchor doesnt mean you cant do OL's group testing method.
If you are consistently shooting left and you find out the bow is tuned pretty good.
Take a look at a few things:
yur body alignment (draw arm, shoulder, arrow alignment). I've never videoed myself but I should!!! It's fun watching everyone else on the shooters forum. Atleast makes me think about what I'm doing when I'm practicing for form in the house.
Are you dead releasing or pulling through? dead release can give you a left impact.
Lastly, and I would check this first, is your arrow alignment. For a right hander, over drawing, you'll shoot left all day long! it's like moving your rear site to the left.
There is a lot of factors, you need to work through them one by one. Bow tuning is where I'd start here, so I should have mentioned this first.
Once the bow is tuned, I'd look at you, the shooter. If you are doing things right....the only thing left is where you're pointing the bow.
I like to bareshaft, then paper tune, then try Ol's group testing. Used to finish on the paper and shoot my bh's before season, just started trying this method, definatly interesting and it works. But I dont like starting off in the blind, breaking wood arrows in hard targets because they are off. Bareshaft up close and moving to paper tuning will help fix this. Ol's method seems to confirm what I'm doing. WOrks for me, my 14 fingers and 5 eyeballs
