OK service seems to be getting better, the shoulder is getting much more relaxed. I feel I was unconsciously tensing up after trophy at max external rotation because of an old shoulder injury (pain at max range of motion). Stretching and shoulder exercises have reduced it to almost nil. Plus approaching the service line totally relaxed and not rushing the toss/backswing seems to have helped me explode into the ball better.

Real time:

Slow motion:

The sharp eyed may have noticed the stickers on me...playing with Kinovea software and seeing of the tracking markers on certain body parts will help with the tracking. Success! So fun hehe:
