I dont know how you avoid parity on 4x4 because sometimes I get cases where there is a 2 wing swap (opposite or knight shape) and I don't know how to avoid or solve that. if you can please tell me how it makes my times like 2 minutes

Anyone know a good alg for these?
And mirror as well if possible

Like LBr's pictures above?

You shouldn't be getting those cases if you're using reduction; pair all of the edges, then deal with OLL parity when you get it. "Avoiding" OLL parity is usually done by solving edge parity together with the centres, but to do that you need to know how to count the edge parity from a fully scrambled cube.

Check 4BLD alg sheets.

The way I'd solve these are:
r2 F2 U2 2R U2 2R2 F2 r R U2 2R2 U2 F2 2R F2
(y') [R' F' : 2R U2 2R U2 F2 2R F2 2L' U2 2L U2 2R2]
which are almost certainly not the fastest.

What should splits %'s be for 4x4?

I average around 42-44 for context.

Cross edges and centres: 21 secs.
Edge pairing: 10 secs
3x3 stage: 14 secs, more or less.

Splits should be 47%/22%/31%. Parity is not included

So it should be like a 50/20/30 split, it may also vary from person to person

Interesting. Your first split is about the same as mine but I average high 40s

From a 46-second mean of 12, frame-counted:

F2C: 4.3 s (9%)
3cross + L4C: 13.4 s (29%)
Edge pairing: 12.8 s (28%) (includes last cross edge)
F2L + LL: 15.7 s (34%)

Probably doesn't make too sense to compare my splits to others' because I usually also solve one F2L pair between finishing the cross and doing the rest of edge pairing.

also I got on-cam-PB single while measuring this but the camera angle is horrendous and you can barely see anything anyway
