Just a side note, when the car drops into aero mode it lowers 15 mm, does that really affect the light thrown by the headlights. I read somewhere that the later models are supposed to know when you are cresting a hill and they lower the beam to not blind oncoming vehicles when you are doing highway speeds
What convinced me to manually adjust was driving in light fog where sometimes high beam is better as the bounce back is not to bad and you can see a bit further, anyway my high beam setting was just shining into the tree tops

My understanding is that the adjustment screw is essentially changing the zero / 'starting-point', and then they will self-level from there. I believe it only levels based on the vehicle's position relative to itself - i.e., measurements of front and rear height - as opposed to adjusting based on the road's incline.
It's actually pretty interesting watching how many small adjustments are made as you travel along - if you watch the beam cutoff on the rear of the vehicle in front, you can usually see it. Likewise you can see it watching the beam cutoff on a wall or the like when raising/lowering the quadralift (incl. into aero mode).
