Yesterday, AL60Ri7HMi57 posted a quick video with new lighting and a clean 22-second solve. In the comments, she wrote, “Do the scramble and post your time in the comments below!” So, I figured I’d give it a shot. I had my camcorder charging on my desk, so I haphazardly aimed it, flipped it on, scrambled, and solved. 35.65 seconds. Not great. But, in all honesty, right about where I am. At least on video. I’m about 5-7 seconds faster off video, without the inexplicable nervousness of being on-cam.
The Video and Initial Observations
My first reaction was to ignore the solve and move on. Rarely one to miss an opportunity for self-examination, though, I decided to learn from it. So, for better or worse, here’s the video.
Some initial observations:
- The production is awful. One extra minute to locate the camera better, move a lamp, etc. would have helped.
- I shouldn’t have used a black cube with the U face gray. Gray U faces work on a white cube on video, but not really on black ones.
- The angle is rather unflattering and makes my arms look crazy hairy.
- Upon further reflection, it turns out my arms are crazy hairy.
Reconstruction (Why I Suck)
Since so many folks had taken the challenge of doing the same solve, I thought this would be a good opportunity to do a reconstruction and see what I could learn by sharing it and comparing it against others. Here are my moves (with time stamps), with the animated reconstruction here:
scramble: L2 U2 B’ D2 R2 F2 R2 F2 R2 F U’ B2 F U L2 D R D B R’
y’ // inspection
L U’ L2 d’ R2 D R’ u’ // cross (4.4s)
y’ U U R U R’ U2′ R U R’ // F2L-1 (7.9s)
d d d R’ U R U’ R’ U’ R // F2L-2 (13.8s)
d R’ U2 R d’ R U R’ // F2L-3 (17.5s)
y d’ U’ R U2 R’ U U R U’ R’ // F2L-4 (22.6s)
y F U R U’ R’ F’ // OLL-1 (#17) (25.2s)
y R U R’ U’ R’ F R F’ // OLL-2 (#33) (29.3s)
z D’ R2′ D R2 U R’ D’ R U’ R U R’ D R U’ [R] // PLL (V), AUF (35.65)
Looking at the video and reconstruction, there are at least a few plainly obvious reasons I’m not a lot closer to 20 seconds:
- I missed that the orange-green F2L pair was already paired after the cross and broke it up when doing the first (red-blue) pairing and insertion.
- My look-ahead is awful. In fact, there is no look-ahead. Each F2L pair is like starting from scratch. And the cross > F2L > OLL > PLL transitions are clunky.
- Because of point (2), I spend a lot of time hunting still. Maybe a total of 5-7 seconds.
- Although I insert F2L pairs into slots other than the front-right, I setup each of the four by starting with the corner over the front-right open slot. That leads to all sorts of unnecessary cube rotations and U turns. (Off-camera, I do this a lot less. But on camera, it’s a disaster.) This is the result of learning F2L based on the badmephisto/Andy Klise sheet, with all the open slots being front-right. I do know F2L intuitively now, but I started there, and old habits die young.
- Two-look OLL. Not just the fact of it, but also that I paused for a while before doing the second of the two. I know a little more than half of the OLLs; #17 is not one of them.
Interestingly, since I just posted over the weekend about my new V Perm, I got to apply it here. That was fortuitous.
