Yeah, I noticed the uneven edge times when I was doing my mechanical testing.

Off the top of my head, I was planning on waiting for a first signal and watch for 2nd signal, then reset loop if no more signals. I haven't done any coding on it yet, but I was planning on keeping it very straight-forward.
