Woooow! My first feel was: HOW?!
Then I found a 100-110 path, then an 80+. Then tons of 80 and 90 +. Only after that I started discovering 70+, and soon after 72 I got 70, as well. I really wonder if there is a 68.
Quite a unique structure, imo (half a star off, for the original record to be so far away. If that wasn't the case I'd give 6 stars, if it was possible. :) ).
