Okay, does this solve the problems? From what I can tell this still increases slope stickiness, probably even more strongly than before, but without introducing issues in evilmike211.j2l or eztrig.j2l. (No other filenames have been mentioned as problematic, so those are the only ones I've looked at.) It probably also gets rid of the "slamming" effect mentioned, but that's just me guessing what that might refer to. That said, there's always the chance this introduces new issues in other areas related to floor detection, so please try it out thoroughly.
