It sounds like you have your level 10 tuned properly. It seems to shoot fine. It is only during rapid fire that the problems show up, which would indicate a feed issue. Check to make sure that the balls feed fast enough to keep up but not at a force that is too much for the detents. This is especially important if the paint is a bit small. You don't want the balls to get pushed forward due to momentum, as the hopper feed rate increases with the rate of fire.
Except for the Automag in front, its usually the man behind the equipment that counts.
