I can't believe that I solved this one within 3 tries... LOL!
I looked at it and "saw" a logical way to do it. Had no big hope though, as my logic rarely lead me to winning, but surprisingly, this was the way, with just a bit adjustment to reach 83. Had no 2 off.
Unbelievable... Had correct route on first try, arriving 2 off, and stupidly, I tried different routes for nothing, since my 2 off was just a minor variation on the very first route I tried... ROFL
No comment on the drama, but I found the level perfectly enjoyable to think through! The two sections had a good 'where am I losing steps' back and forth.
