Humphrey Wittingtonsworth IV | 15.xx CFOP Average of 5. @HumphreyWittingtonsworthIV | Uploaded October 2009 | Updated October 2024, 7 hours ago.
I was going to make a ZB average of 5, but my recognition and recall failed too much. I haven't practiced fridrich since august, and I was surprised that I improved.

The first solve is with a gray type C, with C4Y core/screw/springs, no washers.
The rest are with a storebought, with C4Y core/screw, but with store centers/spring.
The C4Y spring doesnt fit in the store centers, and a C4Y center is slightly larger than the cubies.

Last solve was Winter Variation, 4th solve was OLL skip.
Yes, there is a difference,
