Well, there is a reason why most world records are held by shooters shooting hinge releases, including all the "big" ones:
- FITA round - 1419/1440 (Peter Elzinga),
- 50m round - 715/720 (Chris Perkins)
- FITA18 round - 599/600 (Chris Perkins)
If you shoot with a clicker (very helpful for getting to a fairly consistent "starting point" for your shot execution), then set it fairly hot - you want it to click just as you come to anchor - and NOT (!!!!!!) after you've started aiming. Don't rotate it with your fingers. You have to really REALLY not care where the dot is - no stop / start / stop when it moves away from the middle, just aim and pull and trust your process. This is easier said than done but worth it when it works.
