Have made some progress lowering the X today to default values (my X5 ranged from 735 to 745 mm on each corner when we started, from bottom edge of 20" wheel to edge of fender), however it's not easy, as you have to keep checking by measuring and its hard to lower/raise in small incremements (like 1/4")

Started in Control module functions, where TwinsPoppa alluded to setting the zero point which is the best way to set default ride height, Raise or lower and set the zero point to where you want it, however I'm having trouble getting my corners even.

Right now the front right is just under 28", while the front rear is about 27.5", I'm still searching for a way to get the corners to even out by incrementally raising and lowering in small amounts and setting it as zero point. I've found that the raising and lowering in the control module function does so in 3/4" to 1" incremements, I'd like to be able to fine tune it if I can.

I think the zero point method of raising and lowering the X is a better method than the "tricking the module" method in ride height calibration, where you add mm's to lower the X and subtract mm's from ride height to raise it. I'm borrowing a friend's GT1 tonight so I will either play with it today or tomorrow and see if I can fine tune the ride heights further.
