As you guys may have recently heard, Feliks has been using a technique called "zeroing" during his latest solves. I have written a short bit about the technique including an example, and then made a video from said example.
I hope both help detail the method.

I put it in [ code] tags so it wouldn't do some terrible formatting like it usually does.

Plan for ZZeoring video.
Hello, my name is Stachu Korick, and with permission from Feliks Zemdegs and Jules Manalang,
this will be a short video detailing the Zeroing technique that Feliks has used to get both
the current WR single and average. I will be mainly covering the ZZ variant of Zeroing (ZZeoring).
Although the Zeroing technique was first used for block-builders due to the ease with dealing
with 3-gen phasing for inverse flipping, Feliks has made it possible for it to benefit him
during CFOP solves with speed-optimized primary phasing. Zeroing is only beneficial for CFOP users if their TPS
(turns per second) is rather fast, especially during primary phasing.
Unfortunately, I cannot go entirely in depth through the technique; I have only been able to
comprehend Zeroing in respects to ZZ due to my ill-fashioned block-building.
An important note to make is that Zeroing can be implemented in almost any solving method,
however due to limitations in move groups, certain methods typically benefit more from the system
than others. The two phasing stages, the "primary stage" and the "secondary stage," are to influence
a Block-Setup Last Layer. There is really no good way to explain it in words, so here I'll show
a few example solves and explain along the way what I'm doing.
Before I initiate, let me note that my 3gen phasing is limited to <R,U,L> due to me avoiding reverse
edge orientations.
Scramble:
U' F2 B' R U B2 U' R' F2 U' R F' B2 R2 B' F2 R2 F2 U2 L2 D' F R' F' B'
First, let me note: What's beautiful about ZZeroing is that the primary 6-gen phasing is done during
EOline with no consequence to movecount. 6-gen phasing after limiting oneself is essentially impossible
for anyone to do.
EOline x2 U L2 D' R B D (6/6)
Left block R L2 U2 L' U' L' U L' (8/14)
is what we would do if we were regular solving.
However, with <R,U,L> phasing, we can set up the BSLL for a better alternative with
Left block R L2 U2 L' U' L' *R* U L' (9/15)
Actually, with doing the second phasing before the second block, we can do even better!
Left block+ R L2 U2 L' U' L' R U *R2* U' R' U L' (13/19)
Setup into BSLL:
y U R2 U' R' U2 R' D' L F2 L' D (11/30)
intuitive 2GLL case:
Sune (R U R' U R U2 R') U'
Anti-sune (R' U2 R U R' U R) U (16/46)
Without doing the primary and secondary phasings during the left block, we would have surely not been able to
have a near-complete right-block.
So with Zeroing, the total solve is:
x2 U L2 D' R B D (6/6)
R L2 U2 L' U' L' R U *R2* U' R' U L' (13/19)
y U R2 U' R' U2 R' D' L F2 L' D (11/30)
(R U R' U R U2 R') U' (R' U2 R U R' U R) U (16/46)
Now let's go into Feliks' WR solve.
Direct quote from one of his posts on the forums:
"R2 B2 D' L2 R2 D2 F2 U' F2 D' L2 U B' D2 L' U2 B F R U R
x U2 R2 F U' L2
U R U' R'
U' y' R U2' R' U R U' R'
y' U L' U' L U' L' U L
U2 R U' R' U' y L' U L
r U R' U' L' U R U'
U R' U' R y R2 u R' U R U' R u' R2
55 moves = 8.12 tps."
While he may be telling the truth about the solution, what he doesn't tell is his use of Zeroing! (well, trying to :/)
y' U L' U' L U' L' U L
On that line, one should be easily able to see that a normal person would have done
D L U L' D', but he recognized that the next pair would have ended up in an unforceable second phasing,
which he reluctantly decided not to do, causing the LL to be just normal CFOP.
That's all I can cover today; explaining this has been a bit of a trouble, but I hope it helped.
Perhaps one day hopefully soon I shall be able to take apart Rowe's recent 6.94 official solve and explain
his personal phasing technique.
Just as a quick note: you as a member of SpeedSolving.com may have heard of Anthony Brooks using Zeroing.
Due to the recent collective development of 3-gen RUL phasing and 2gen RU phasing, he has made decent
progression in his one-handed solves, but has not yet unlocked the full potential of 3gen reverse (and inverse)
orientation.
A quick collective list of Zeroers to date are as follows:
Feliks Zemdegs
Jules Manalang
Stachu Korick
Rowe Hessler (only recently integrating it into solves.)
Anthony Brooks
