Are xenon legs supposed to be the same length. My Xenon is set at about 5 to 6 degrees incline, but that makes the fronts leg levelers all the way screwed in, and the back are all the way screwed out. Is this normal ? The back leveler's look like they're going to fold over at the slightest push they are so far out. Both front and rear leveler's are 3". Is the playfield supposed to be level with the glass ? Or should the playfield angle more than the glass ? Or should the rear legs be longer ? Is this how everyone's is ?
