Right flyers for me usually happen when I do not tilt my head with the cant, and as mentioned from not releasing the tension in my draw hand before releasing. I can release the tension without releasing the bow string. But, if I think about the actual release at all, I'll screw it up. If I get a bad release, my arrows usually go a little high and left.

For the cant, as another anchor point, the string usually just touches a little above my eye. This is also a good reference point for me for short drawing.

Also, make sure that you are using the exact same form for the 10 yarder as other distances. Sometimes, people get into the "chip shot mode", and something in their form goes.
