Yiheng Wang's PLL Time Attack Sequence

[Patoony]

3x3 noob here! Is anyone able to tell the order of PLLs Yiheng is using? Youtube links below for reference:

Thank you in advance for the help!

Slowing it down to 0.25x speed, from what I can see (this is from the 18.67 video):
Gc, Gd, Ga, Gb canceled into Ub canceled into Ua, H, Z, Ab canceled into Aa canceled into E, T heavily canceled into Y, F, V, Ja, Jb, Rb, Ra canceled into Na, Nb
idk if these cancellations should be allowed, don't really know the full extent of the rules of a PLL time attack but I think the entire alg should be performed in order for it to count. I can provide a full reconstruction if you guys want to be able to see the cancellations

I see! Thank you so much for the insight! No need for the full reconstruction but if you don’t mind sharing just some examples of what cancellations look like, it’d be greatly appreciated!

idk if these cancellations should be allowed, don't really know the full extent of the rules of a PLL time attack but I think the entire alg should be performed in order for it to count.

Obviously it's an unofficial event but I think it's generally been accepted that no, cancellations aren't allowed. From the 2013 time attack thread:

Rules are you much do all 21 PLLs, in any order you like. Move cancellation is not allowed.

I can't see any disagreement anywhere.

Oh, and this from 2010, if it's helpful:

you can ignore any pre or post AUFs completely

Which I know was debated but I'd say is generally agreed also.

I made a reconstruction of the last video, the short where he's wearing that red thing around his neck. First here is the sequence of moves that he did:

Next, here is the sequence that is implied, without the cancelations:

You can see he does the following skipping of moves and cancelations between PLLs:

• Cancels from Gb into Ub with an E move
• Skips R R' moves at the end of Ub to cancel into Ua
• Between Ab and Aa there is no R2 R2. He just does a D4.
• Skips R' R in transition from Ab to E
• The T+Y become some kind of 22 move Ja perm.
• In the transition from Ra to Na instead of ending with R' U2 R', he ends with R' U' R' so that he can skip the first three moves of his Na permutation.

Note that the directions of some half turns like R2 could be wrong in the replays links, please ignore that.

Edit: Just wanted to clarify how the T cancels into the Y, and make that '22 move J-perm":
R U R' U' R' F R2 U' R' U' R U R' F' F R U' R' U' R U R' F' R U R' U' R' F R F'
R U R' U' R' F R2 U' R' U' R U R' R U' R' U' R U R' F' R U R' U' R' F R F'

Thank you for this!
