fairly balanced sections in terms of difficulty
for left upper part, the wrong idea seems quite far off - of course if you are experienced you probably know what to do early
In my previous sessions I couldn't get close before seeing this main idea. Then I saw the 128 today, took several tries to get the good sequence to get 126.
I was never 2 off, I went straight from 4 off to winning. I found the piece of path allowing to win by doing it on a wrong route, and noticing how nice it cuts. I then try it on a different route and it worked. Fun all along.
