Don't know if this will help, but here is what I do with my students. Ground work is FREE all it takes up is time, I spend atleast a half hour with my student on the ground going through the dive (do this for each level) what is expected and how to acheive it. Ask your coach about the "mantis" body position as this is the ideal time for you to transision to it, before you burn in the box position in to memory. The advantages of the "mantis" are increase visibility, better grip management, more power in legs, faster centre point turns. Spend as much time as you need on the trolleys, ask as much questions as you need, and if your coach does not know the answer, ask somebody else. Check with your CI for his approval on the coach, as there are a number of jumpers who will help you out but teach you nothing. Also get the coach to give you a detailed de-breif. If in doubt, whip it out.
