I'm averaging ~2:15 on 4x4 with a weird Yau-Redux combo. I do Centers->White Cross(edge pairing)->3-2-3->3x3 Stage. I do that because It's like 30 sec faster than me just doing normal Yau, although I don't have much practice with yau. What should I be practicing to improve? Also, my 3x3 average(3x3 puzzle, not 3x3 stage) is ~20 seconds.
My advice is you should do the full Yau method.

White/Yellow centers
3 white cross on the left side
Last 4 centers
Last white cross
3-2-3 EP
3x3 stage

Your time will get worse at first, especially in the part of the 3 white cross, but over time, it will be very fast.
Is that not even when you switch from layer method to F2L at 3x3, at first your times will get worse, but with a lot of practice, your time will be so fast.

I can't do the last white cross on the left side, i need to rotate, but i will practice soon.

This is my experience, I'm new at 4x4, but practicing for 2 months and I my avarage is 1:15~1:20

Just practice normal Yau. You can get sub 1:30 really easily with some practice.

Hey,
I'm finding the way I do the Edge Flip alg really slow, with 3 REGRIPS, and I believe it increases my time a lot when there are some cases in a solve.

The alg i'm using is:
R U R' F R' F' R



Here is a video of my execution, first slow, showing my regrips, and the last at normal speed.




I wonder if there is a better way to do it, a better alg or a good fingertrick
Tks!

Watch any fast big cube solve in slow motion to see how the pros do it. I think your execution is fairly close to the standard one, so you probably just need to drill it a bunch; the F' with your right thumb shouldn't really be a regrip.

Alternatively, you can also try R' F R F' R U' R'. The fingertricks for this should be fairly obvious: just do whatever you do for a sledge, then whatever you do for a 3-move F2L insert.

Thank you!!
I will watch, and keep practicing!

Do you use 3-2-3 or 6-2 edge pairing?

What are the pros and cons of each?

Is one better than the other?

3-2-3 kills the two back-slot blind spots earlier and thus provides better lookahead, in addition to having less weird cases to care about.

6-2 is probably slightly more efficient on average, but as it requires a ≥6-cycle, weird cases show up more frequently. On the other hand, it also makes better use of pre-paired edges compared to 3-2-3: if you have one free edge pair, 6-2 becomes just 6 (one step), while 3-2-3 becomes 3-2-2 or 2-2-3 (still three steps).

(I'm a hipster and do 2-4-3 instead of either of those.)

i don’t think it’s possible to have an impossible EPLL case with more than 2 incorrect edges, can you describe it? i might be mistaken

I was doing a 4x4 solve and when I got to EPLL, I had an impossible case(no Z U or H). After doing PLL parity, I had adjacent PLL parity with the rest solved. Why did I have to do double PLL parity?
Because you messed up somewhere.

The two main possibilities I can think of are:
(i) You executed the PLL parity alg wrongly, and it ended up not fixing parity the first time you did it.
(ii) You did really have a U/Z/H perm, but misrecognised it.

What do you mean by that? Doing adjacent parity instead of opposite?

It's possible it was a Z-Perm, but I'm pretty sure it wasn't. It doesn't really matter overall anyway
