Jack,
Great response regarding the clicker and Olympic archers and please understand I'm not disagreeing with you because you are right; a clicker will help your form and back tension. However I will say I've tried the clicker and I've got the collapse so finely tuned, after 10 years of doing it wrong, I didn't notice it until I watched the tape. I'd here the click go off but I can hold afterwards and collapse so quickly I wouldn't notice the next click resulting from the string going forward before the shot! In fact I didn't even hear it on tape it's so close to the release but visually, in slo-mo, it is there.
I do believe the clicker is a great tool to improve form and back tension; but the clicker is just another wrench in the box and we've got to pay attention to all these other little things such as grip, follow through, concentration, head position and so on. I know this challenge is why I love shooting recurves and longbows!
