@J_L that is perfect, nice one.
So in essence you can compensate too short or poorly positioned foil tracks with the shim to manage a takeoff.
When up and riding, ideally the deck and foils are parallel and you rely on the foil designer to have optimised things, and not need much shim for the designed context, BUT if you do need to change the feel, you can tweak things.
fwiw I updated it with your and @KDW insights, thanks both.
