This was a long grind. Took me about an hour of routing/strategy testing, and 10 hours of grinding to get this far. I actually got two WR's earlier today which I'll link (but not submit to the leaderboard)

11-1: 6.21 (Best is 6.17) 11-2: 14.16 (Best split was 8.00, but this is a record. 7.25 actual) 11-3: 22.27 (Best split was 8.08, this was an 8.11). The WR could be lowered to 22.20 at least... maybe more?
