Quoted from kermit24:I’m think that Karl moved the guide towards the player so that the ball makes more contact with that rubber ring. I actually moved my guide towards the back of the game and now it always goes in the right inlane.
75% of balls exiting from my upper playfield were draining out the right outlane, even with nudging sometimes, and this was with the ball completely missing the rubber due to the factory rail setup. The rail has some play designed into it for adjustment to prevent this I assume.
