Didn't think this deserved it's own thread.... but is it ever necessary to retreat on L3 springs? I only died on 1 spring board during the entire KO4 and it was on L3 lol. I usually run on a long spring and don't look back... that seems to work 99% of the time. But sometimes/rarely if the next spring is very long, I get hit. I'm guessing I didn't get a good enough head start and it should always be passable.
If you get a bad jump on the shortest-longest combo on L3 you can get tagged. Well, with a bad jump you can get tagged on any combo on any level, really.
Anyway, with a [0,14] and [0,15] combo you have to be frame-perfect and hope that Jumpman's sprite-drawing routine doesn't delay you by a frame. With [1,14] and [1,15] combos you have an extra frame of wiggle room. Those 4 combos are the most dangerous on Level 3. This is assuming the standard approach from the left-side safe spot. From the right side, you can never make it on [14,14], [15,14], [14,15], or [15,15] combos. Right-side [13,14] and [13,15] need to be frame-perfect and [12,14] and [12,15] have an extra frame of wiggle room.
