Quoted from arcadenerd925:
I gave in and tweaked the TNPLH to be as easy as possible, heh. gives me more of a chance.
Mine was like that in the first dozen of plays. Then it improved, maybe the mechanics of the bumper getting into better shape, but now the save rate is around 40% I would say, which is nice. Completing "Over the rainbow" is another story though, that left loop shot between the bumpers is very difficult
