[ottozing]

i think avoiding oll parities is the new zeroing (if you know what i mean).

[Reinier Schippers]

Getting lucky is not a crime right erik?

Notes:

Spoiler:

Scramble with White on U and Green on F
Move counts are estimated using STM & ETM
All notation is SiGN
Wide and slice move examples using SiGN notation: alg.garron.us
Rotations may not be actually what was performed
Moves and rotations in ( ) are executed simultaneously
"F2L" in the statistics refers to the four courner-edge pairs only
Thank you to Erik for the scrambles

Thanks Brest! Now only to find out how to avoid those OLL parities.
Edit: Now I feel stupid.
