I quickly grabbed a piece from an article I wrote a while back; some of this may give you an insight on your question
I hope it helps.
I prefer mine set “Hard” be it the Hinge, Thumb release, Evo
Setting it up so it fires without much effort – a “hair trigger” works fine for a while but usually tends to make a person anticipate the shot, builds paranoia over miss fires while drawing back and letting down and causes some shots to be premature - firing very quickly while settling into the X
When setting up a hinge or thumb release that has more hang time or travel while pulling thru the shot helps a person stay stronger thru the aiming process of the shot thus helping a person from having a “weak shot due to – pre-relaxing of the muscles while still aiming” Versus staying strong and somewhat stable thru the whole shot process.
You will see at times when some of us shoot under pressure in a shoot off where we have to let down because of the shot not going off as wanted “we will then switch to a Harder release - more travel or effort needed before it fires” in order to stay stronger in that high pressure shot thus scoring better under pressure. Most people think that we are switching to an easier release when it’s actually the opposite.
Have you heard the saying? - No two people are ever alike; everyone does have their own unique personality. This statement carries a lot of weight when it comes to one being able to understand and repeat in a physical manner what he or she has been taught.
My old saying here is Archery is 95% mental and I still say this is close to being true yet today. Truly the only obstacle that most have to get by to achieve what we all desire is the space between our ears. Being that we all have our own unique personality affects on how we interpret a command, how our mind reacts to pressure, how we stay focused, and most of all how each and every one of us can try to stay relaxed versus being nervous.
We all have the desire to shoot well, one simple step will turn one individual into a shooting machine where as this won’t do diddly for the rest of the archers that are working their way up.
I myself many years ago shot back to back 55x -300s at the nationals and I did this with my hunting – target release a Scott Mongoose caliper release triggered with the finger,
I went to a back tension to try to get the last couple Xs more consistent.
