I don't think either of you is wrong. It probably depends on the person and equipment used and other conditions(fatigue most likely):
Compare this

To some of these releases from 3 different people taken over a period of 1 afternoon distance shooting and target shooting:

You'll notice that even the same person has variation on the releases. The only one that is close to consistently 'jerky' is the guy with the massive 125lber. You have a variety of releases. You have one where the hand travels with the string, you have one where the guy releases laterally and one where the hand jerks. All these things happen to different degrees in each shot.
So really the correct solution would be to have many diifferent animations for different bow draw strengths but I suspect that would be a lot of effort.
Looks good non-the less.
ps. The guy in #1 kinda has a woosy bow compared to the above.
