This was a really interesting one where the optimizations kept trickling in two steps at a time. No one big a-ha moment, just an occasional slight cleaning of the path. Lots of possibilities here and everything does a good job of getting in the way.
I can hardly believe how stupid I was... I was straight 2 off and from there, struggled a long time simply because I kept focusing on wrong location to save 2 steps... Only after I forced myself looking elsewhere, I got rid of the 2 steps on next try... Idiot me! LOL
