I thinks there are too many awkward cases for 6 at a time on the 5x5 for it to be efficient.
Yes, you are right about this for the technique that Erik is using.
There is another approach though:
- solve outer edges using the 4x4 technique (6 2 2 2)
- solve center edges with the outer edges using the 4x4 technique (6 2 2 2)
One bad thing is that if you end up with a parity it is one of the awkward ones.

Have fun,

Ron

Ha, I was dismissing that wing-middle approach while suggesting it to qqwref. :p

I think this idea came from Alexander Ooms, but when I showed him my method he liked it better. The problem with solving outer edges first is that you have to find the matching outer edge, which is 1/23. With my method you only have to find the center edges which are 1/11.

Nice video's Erik! I will switch to the M-layer eventually, it simply gives better look-ahead and better fingertricks.
And just so everyone knows, this is how I start the edge-pairing:
Look for a semi-pair during the final centers. If I find one I use it.
Otherwise I just match up the first two semi-pairs (forward and back) without having a semi-pair at the Front-Left position. After the first match up there will be a semi-pair at the Front-Right position, so I just do z2 to put it at the Front-Left position.
