To be quite honest, in my opinion the best thing you could do would be to walk up to your instructor and say straight out that you are having problems with this (he will know that) and that you would really like some help in coming to really understand what you are doing and how to do things quickly and accurately. That's what he's there for.
In my experience, he will be glad to spend some extra time with you and he'll also appreciate both your honesty and the fact that you are aware that you are not quite cracking it yet.
That would be a MUCH better way of getting it sorted than coming into PPRuNe and getting what will inevitably be a morass of contradictory advice and "tips".
Bite the bullet and do it.
