Cleared this guy for my 2,400th clear. Its extremely well optimized and exceedingly tough. Props to Dgriff for catching all these nuances. There are bits where I think some people will see things faster then I did. I had a lot of trouble just spacing out while playing this.
A small edit to this. After some discussions and a bunch more runs after the initial solve, it appears that there are 2 EXTREMELY different solutions that both come out to 705. I almost can't believe there isn't another 2 cut lurking. bumped down to 4.5 because I'm mad about double solutions.
