You are still going from 0 to 10, but you only have enough time as you have cut out for. Loading the line - The loading of the line comes from a progressive edge. This is called line tension. You'll know if you've got it because at the top of the wake, right before you release, you will feel a lot of pressure on the rope. This increases on the tricks like Raleys, where you have tons of progressive edge and TONS of line tension.
All tricks require some line tension.
The key is a solid, slowly-built edge. A great way to get a feel for it is to drive someone that can really ride. The boat will slow as they approach the wake and speed up as they get airborne. A great rider doing a big trick will pull the boat super hard to the point that the driver needs to speed up during the trick. Someone who is not practicing this will jerk the boat and you will not see the speed change at all.
