For my method: 1) works fine 2) works fine (so long as end > start, if not it's trivial to change) 3) fails, you'd have to use a different method or combine it with another. If you're not looping you could change the detection to something like "b - a > 0.5" to detect a large drop in one frame (which would be the end of the loop unless you have a really extreme curve).
