I jumped the gun a little and forgot to reset the medium sized channel. A lot of time internal data flow indicates channel lines. I relaligned them and they point to my predicted top better. Of course I MADE that happen. So go with your own bets. I also adjusted the arcs. The arc to the bottom matches the 1st highest arc distance, if my predicted top is right. I would look for a channel break at the top. If it breaks my purple channel by even a small amount, then I'm wrong.
