Quoted from koops:You need to re-calibrate your phone via the button in the app. There is no way in hell that machine is on 13 degrees with the front feet wound so far out. It would be closer to 5 or less which would make the game very slow and floaty.
Put the level on the PF not the glass. Should be between 6 and 8 degrees. 13 could only be the glass.
I put my front all the way in (down), and the back legs almost all the way up (about 1.5 inches of threads exposed).
Back levelers:
Easier is about 1 inch of threads showing ~ 7 degrees PF pitch
Mine at 1.5 inches of thread ~ 7.5 degrees
hardest is 2 inches of threads ~ 8 degrees
