Could someone please give an explanation of Non matching centers? I've been trying to incorporate it into solves but I'm not sure if I understand.

instead of the regular center on top, put the nonmatching center on top. orient everything in relation to the nonmatching center colors. since the UL and UR pieces won't have those colors, just use normal orientation. everything is that same after eo.

these are the only times i use nonmatching centers:

example (80% of 6 flip cases):
scramble: R U' r' U' M' U r U r'
solution:
U' M' (UL and FD are oriented) (UB, UR, UF, DB are unoriented) thus, 4 flip
U' M U' M' (everything oriented)
(UL and UR pieces are at FD and UR) U' M' U2 M' U' M2 U' M' U2 M' U2 M'

example (easy four flip case):
setup: (M' U')x4 (M U')x4
solution:
U' M' (everything is oriented)
 
For an alg such as this CMLL H 2:
y' R U R' U R U L' U R' U' L

What is the meaning of the first step being y' instead of U'?

Also is there an easy way to tell what part of an alg like this to use for spamming in short loops (returning to initial position)? It seem you often need to add or omit a first step to get it to loop properly but I don't see a pattern for determining that.

Damn, I just learned that one yesterday but I learned a different one. If you apply that alg to a solved cube, and have a look if it messes up the bottom two layers at all. If it doesn't, then you can just use U' rather than rotating.

if you repeat any alg over and over, you will eventually come back to the solved position.

Its to save on the AUF, but in roux it barely matters at all (cmll isnt the last step of the solve). I use U' yeah.
