Begining my second round of shockwave therapy, how to maximize success rate? (2nd time lucky hopefully)

I had shockwave therapy about a year ago and it wasn't successful. Since then I have lost about 10kg and a consistent regime of stretches and strengthening.

This hasn't been enough to eliminate PF.

I'm starting my second course of shockwave therapy (3 sessions). I plan to lose more weight.

Any other suggestions?
