[WR] Feliks Zemdegs - 21.54 4×4 single

So I'm a bit confused at how he is pairing edges. I am not that advanced at 4x4 but I thought he does something like slice followed by inserting dredges into the other three spots so they pair up after slicing back but this just looks like he's pairing up one at a time. (I apologize if I should just post this in the help section)

I think he had some edge cases that were simple or he's turning too fast for us too see. Brest has a reconstruction up so that may help you see.

Ya, I was watching the reconstruction and that is what got me confused. It might have just been some easy cases unless he is doing something I don't yet know/understand.
 
[WR] Feliks Zemdegs, 4×4 single: 21.54

I expected the 4x4 average to be beat before the single; it felt more reachable. The numbers agree with that; the gap between the 4x4 single and average was and is bigger than the gap between 5x5 single and average.

Luck with parities and during other steps is the main reason for the large gap between single and average.

Luck tends to average out more on larger cubes.

And then there's the 7x7 WR single. Not really sure how to explain that. Let's go with Faziness.

He saw it was 1 dedge solved, so he did 3-2-2 edge pairing. I suppose you could define what type of edge pairing someone is doing by how many edges they solve between when they first slice and when they finally slice back. As you'll note in the reconstruction that he placed the GO edge piece after the slice move so that it *would be solved when centers are finally re-aligned*, but noticing that the RB pieces were ready to be paired as well in those inner slice layers, he formed it with 'u d' (not messing with the positions of the to GO edges), and then noticed what the solved RB dedge needed to be swapped with (the other YG edge) so that when centers are realigned, it would form the YG (and first GO) dedges at the same time. That's the tricky 3 edge part. The remaining 2-2 are pretty standard
