The angle on dishpointer is the angle from the horizon up to the satellite. It is a calculated value. How accurate, I haven't a clue, but always useful as a guide.
The angle given is not the same as you need to set, as you have a motorised dish. The shaft sticking out the motor is not necessarily vertical, so the elevation markings on the dish will not correspond to what dishpointer says. The angle of dish face however will be as though it is on a fixed mount, when set up properly.
For example if you stuck your dish on the top of your wall bracket, and set the dish elevation to 30, that should be roughly right for thor and that is how the dish should look when its on the motor (when the motor has been sent to Thor)
