I would highly recommend getting used to not using cube rotations (even when you are just searching). It takes a while, but in the end it will be faster than thinking about cube rotations, and NISS and insertions are painful with cube rotations.

I never understood why not writing rotations was hard o_o

If I had taken the time to find better insertions, I probably could have gotten too at least 30 but I'm ok with this. What can you guys find?

New PBs!
Mean of 3: 25.00
Average of 5: 26.00
Average of 12: 26.80
29, 26, 25, (DNF), 26, 29, 28, 26, 25, 27, (23), 27
Note: I calculate my PBs by saving every single solve that I do in a big session, so this includes three official solves.
The DNF should have been a 26, as I had an L3C in 20 moves with 5 minutes left, which usually is more than enough, but I failed.

Edit: Rolled out the 29 with a 27, so 26.60 Average of 12!

Well, I don't really want to moan and complain, but my two last solves for the Berkeley FMC has contained skeletons where the human of doing the insertion that cancels the most moves first has not only produced sub-optimal solutions but actually 2 and 3 moves away from optimal. Does anybody have a rough idea how likely this is?
