The BEST WAY to shoot a THUMB BUTTON release 

It’s fascinating the most minuscule change can make such a difference. Good or bad. I like to have a relaxed hand so it’s flat. With zero thumb button travel and light tension my break movement ( in slow motion phone video) is barely perceptible. The shot break is to the point that it comes as the pin has settled into its smallest float pattern. I try to never force the pin into any spot but have my body and form so that the pin naturally settles where I need it to. I’ve learned body positioning to the target is crucial to not be forcing the pin. On 3-d targets it works great if I can actually see the rings. When I can’t see them I don’t fight the pin into a particular spot but just let it float hopefully inside the 10 ring. 👍👍
