Okay the 417 is tough particularly because Pathology/Psychopath teaches you how to pipeline for like 90% of the game and then there are levels like this that just subvert some of the fundamentals in weird ways. Easy to understand once you see it but you can be blinded by your pipelining experience.
I may start being of the opinion that PP1.5 pipelining is the hardest thing in this game.
I was 2 moves off when I got 433. Cant remember the path I used. I found a nice pipelining shortcut. :-) May not be optimal, but its about the same as YFKDs record.The levels not great but its depth to it that I dont understand. Current record has 3 or 4 transpositions.
