Yep, I feel ya, pard. After re-starting Trad 2 years + back, I finally put this together about 6 months ago.
Power transfers from shoulders/arms to back muscles about half way through the draw to anchor. At full draw it's all back tension and upon release hand pulls straight back & ends up with the thumb on top of my shoulder. Bow arm follows through and stays pointed at target.
Literally resulted in instant smooth release, more consistency, and accuracy increase across all distances I shoot...
