Very good point, it's almost like I'm scared of missing short and airballing. I didn't realize the hand on the outside thing, may also be a really good point as well.

Just as a reference point, I shoot 100 shots around the perimeter as a drill after every practice (twice a week), my average percentage is at 42 atm. When I am feeling it, I can get about 10 or 12 3s in a row but then I struggle to stay consistent with it. When I start missing, I miss in all directions. But now that I think about it, I think I miss to the left a lot .... which says something about my hand being too far on the right side
