Only today did I finally manage to get this monstrosity at least under 400 (already well over 9 hours in, in 4 sessions).
I pretty much agree with what manti wrote here.
Will keep trying to go lower than my current 395.
EDIT1: About 3 more hours and I am now stuck at 385.
Realized I never reviewed this when I solved it.
This took me a long time to get under 389. my path was so convincing and i just didnt see any areas to cut steps. I finally found a cut and stalled out at 385 but everything felt too loose and then hours after the solve at 385 finally found how to tighten things up.
A really nasty level. Its super busy and difficult to construct a feasible path, not to mention trying to create "the best" path.
