The reconstruction thread

Hi forum,

I am attempting to reconstruct J Perm's third solve beginning at 1:12 in this YouTube video of his:

Scramble: D2 R2 D' F2 L2 B2 U2 F2 U' B D R2 F2 R D2 L' U B' L U

x // inspection
D L' U l F' // cross + one preserved F2L pair
U R' U' R2 U' R' // inserted two pairs back to back
U U'...

This is all I have so far. His hand blocks the view and I can't continue transcribing the reconstruct. Does anyone have any clue what he may be doing to solve the last two F2L cases?

Thank you,
Steve

U U' L U L' L' U' L2 U L' // F2L 3
L' U L U L' U' L U2' L' U L // F2L 4

Generally it helps to do frame-by-frame analysis by pausing the video and pressing . or , to go forward or back one frame, respectively.
Youtube can do frame by frame? I never knew that. Does it have to be with a physical keyboard? Because I am trying to do that with my phone but the virtuap keyboard isn't there.

Thank you all for helping me reconstruct this.

So at a solve time of 6.65 seconds with 52 move count total his turns per second was 7.82... omg.

My 5.72 PB single was 8+ TPS, top level speedcubers often have 10+ TPS during solves
I timed an Na Perm just now to see how fast my turn speed is during that PLL algorithm, I did it in 1.963 seconds with 21 moves.

21 ÷ 1.963 = 10.7 TPS? (rounded to nearest tenth)

But I bet top level cubers have even higher TPS for their last layer algs.

Nice. Yeah, top level cubers can reach upwards 15-20 TPS during last layer.

Only one rotation for the whole solve!! That's amazing. Btw you could have eliminated the rotation by using F' U F instead of y L' U L. Nice solve nevertheless.

3 move xcrosses should be illegal. 1.867s C+F2L, 2.067s LL.

I see two.
