I was squaded with a national FT champ one time, the guy was shooting a highly modified Steyr LG100 with 1-ish oz trigger. I'd watch what he'd do concerning the trigger, and it was all punch, lol, he didn't even take up the first stage. Basically the trigger was so light that he had no choice but to shoot that way. Of note is the lock time on this rifle is fast, and the barrel is short. Both those attributes help make for a more forgiving rifle to shoot. BTW he won this two day wildcat FT match which was quite prestigious and known for being a windy place - at LD's.
I had a LG100 that AZ modded, for 4-5 years, and can relate to how that guy shot because I could get away with doing the same thing he did, and doing so I won a couple state matches with my Steyr.
My USFT, which has other strong points to it, and has also won me state matches, is the opposite of the Steyr in various ways, and I use a different technique when I shoot it.The early ones, which I own, have a long barrel, a slow-ish lock time, and a 10 oz trigger. I flat out have to start a slow squeeze, and let the shot just happen, this while using good follow through, ooooorrr else,! It's the form I've had to develop with this rifle, and well it's the same form I've used to win long range championships with a centerfire. Of course I can't do this technique in offhand or kneeling, which involves timing the shot and a quick push of the trigger.
If I'm relaxed and comfortable I don't need to attempt timing a shot between heartbeats because I'm well within the wobble zone that will make a clean hit. I usually don't even think about my heartbeat while shooting.
If I'm not comfortable, as well as a bit nervous, I need to try to time the shot somewhat because I'm "that" wobbly. I hate it when I'm in this mental and physical condition, with that higher heart beat present, because it's something I don't ever think of practicing, nor want to practice! It'd help if I wore a shooting coat ,etc, but I don't like wearing them. Heck the last 4 years I've been shooting freestyle off a tripod mostly. 'yes I'm a rebel

', and I sometimes get nervous enough that I can see twice the wobble than if I'm relaxed. I'm not so much trying to shoot between heartbeats but trying to break the trigger when the reticle hold is where I want it.
Ehh, I'm not a serious enough competitor to worry about this subject. I just adapt the best I can and it's going to be what it's going to be.
