What is it you are having trouble with? Are you having trouble early, hand signal trouble, or getting back into parade position?
If you are passing the lead, once you look and signal, keep looking at the New Lead. Don't let your right hand follow your look, you just came from "perfectly trimmed up as lead" right?
Control inputs . . . teensy tiny for separation.
Power reduction to start going backward and down . . . small to drift rate is slow.
Patience: Much.
Don't rush it.
As you slide down, then back, and approach the parade posit (still 20' stepdown?) lead with a slight power addition to stop aft slide, then re correct power.
Just general comments.
Is your IP trying to get you to do it faster or smoother?
Or, have you not flown form yet and you need gouge?
