Personally, I think that as a Driver you develop over time, it's more about feel, obviously there is useful information and tips that can help, even when not in the course, where you position the boat and how you approach the the course, is just as important, throttle control, feeding that throttle in, so that Zero Off engages smoothly, before you nudge the throttle forward so zero off has full control.
Small things, but they make life easier for the skier, if you position the boat, so the skier is on the left before you go, this means they do not have to move across the wake to setup, a good thing if the lake is short, when they drop in, give them a little bit of slack line, so that they can relax in the water and gather their thoughts.
