I have struggled for some time not reaching full anchor when shooting at the foam target. I tried everything from video advice to calling Rod Jenkins, Viper, Terry,.. and no results - not that their advice was off base.
The other day I was out shooting and something Rod said popped in my head and that was trying a different hook on the string. Normally, I would pull the string from the first three knuckles of by hand. I tried a deep hook and things just fell in place.
Still shooting at the same target with the only change being the deep hook. Shooting these days is way less frustrating. I hit the solid, repeatable double anchor every time now. Wooo Hooo!
