Keyhole F2L Contest

[CanadianPires]

In the spirit of mini contests, here's another. Just solving the F2L, but using keyhole method. Its gotta be cross -> 3 corners -> 3 edges using keyhole/working corner -> last C/E pair any way you want. Basically, last pair doesnt have to be using beginner alg. Here's my times and the scrambles, not too bad seeing as I usually avg just under 20 for F2L...

This should be fun for Arnaud, considering it just means doing his normal solves.

18.15, 22.58, 23.38, 19.30, 22.80, 16.41, 18.71, 20.25, 27.86, 18.81, 23.43, 21.56, 21.34

20.69 average.

Using 2LLL is sort of cheating

 

[CanadianPires]

lol you don't have to do full solve, just F2L.

 

[masterofthebass]

O Those are full solves, using keyhole + OLL/PLL. O well.

I've tried some key hole a few days ago, counting moves, not timing. Surprisingly, the average move count was about 3 lower than Fridrich F2L. It was like about 29 moves. There's lots "multislotting" and partial LL control you can do with key hole. Like you can insert 2 edges and one corner at the same time, if you set up with a D move.

Yeah, I really liked this challenge, but because of the rules I couldn't use tricks like "attach a corner during the cross" and "unmatched corner+edge pair".

First, I did all 12 solves with F2L only. After that I did them again with a full solve and I was very happy with both results

F2L only:
Times; 16.27 14.50 14.75 11.03 17.43 14.88 12.15 14.69 15.66 15.47 14.25 15.77
Min/Max/Average; 11.03 / 17.43 / 14.84

Entire solve:
Times; 25.78 21.91 24.71 22.81 20.91 16.96 21.44 23.91 24.21 21.61 21.9 22.58
Min/Max/Average; 16.96 / 25.78 / 22.60

The 16.96 full solve was done with edge-control that gave full OLL-skip and an H-Perm for PLL so it was basically a 1.25 look last layer instead of my normal 3.5 look last layer.

Thanks to this challenge I know that my last layer takes about 7.75 seconds.
