Oh also, insertion finder didn't find anything for this one; can it not do 5-cycles of corners?

worked fine for me, it also got 26

[hagner]

while i was at my last comp i discovered that all scrambles for fmc started and ended with R' U' F. ive now looked at every comp fmc in the wca export file and in the last year 99% of all fmc scrambles have started and ended with R' U' F, before that they start and end randomly.

what is this???!!!

It was a new regulation introduced last year which put an arbitrary set of moves before and after the random state scramble itself so as to prevent parts of the scrambling algorithm from being used in the solution. This was prompted by a solve in what would have been a WR mean by Linus Fresz where his first 11 moves matched the inverse of the scramble.

Correct, but I just want to clarify that Linus didn't do that on purpose. But the regulations state that this leads to a DNF, even if it is done unintentionally.
