Yeah I'm just bad, ignore me.

Your F2C seems fast enough though, work on edges a lot

I'm switching back from yau to redux so we'll see.

7x7 help

I just recent got myself a 7x7 and before I scramble it, I want to know if there's anything different that I need to know. Yes I can solve a 5x5, and I've heard that the 7x7 is like that, just more tedious.

The only thing is commuters for the last pieces of last two centers. You may find that you are stuck with a few pieces that you may not be able to solve intuitively at the end.

A Question About 5x5: Completing Last Few Tredges

I have a question about solving the last few tredges on a 5x5.

I am already familiar with solving dedges on a 4x4. I usually solve dedges one at a time, but then set up the final three dedges to solve simultaneously.

For 5x5, I tried doing something similar. Once I got down to 4 unsolved tredges, I tried solving 2 out of 3 pieces from each tredge, so that I could treat them like dedges and just apply the same logic I use on a 4x4. The problem is, I always end up with one completely unsolved tredge, so I can't quite get to the state I need to solve the last three tredges intuitively.

Since I couldn't figure out what to do, I just kept solving tredges until I got to the final 2, and then used the algs on Sarah's cubing website for the case I had.

My question is: Is it easy to do it intuitively like I do on 4x4 if I just keep at it, and figure it out, or is memorizing different cases for last 2 tredges and their respective algs the way to go?

There is an easy way to solve the last two tredges intuitively. You might get a parity case though, I think you need to memorize one alg to solve that.
For example, when you have 2/3 pieces built of a tredge, you can slice the missing slot away to the edge where the 3rd piece is, do the edge flipping alg there, then slice back.

Yeah that's the technique I use on 4x4. When I'm down to 3 remaining unsolved dedges I slice to complete one of the three, then move it up into the U layer and bring down the third one, so that when I slice back it completes the 2nd to last and last dedge at the same time. Are you saying this can be done on 5x5? That's what I was trying to do, but couldn't get it to work out just right. Sounds like maybe I just need to work on it more until I can figure it out.

What about this for example?

I average around 7 on 7x7 and nearly have sub 1 centers.

Really...

If you read the context, it's actually just F2C and not all centers.

That's pretty insane. Unusually slow with pairing.

I use commuters for all the centers :/ why I average 10 minutes lol

Ok, but 'centers' does imply all the centers, not just f2c.

Hi guys im a Little bit stucked at 5x5 can you help me:
F2C: 20 sec
L4C: 30 sec
F8E: 1:30
L4E: 20 sec
3x3: 30 sec
Total: 3:10

What should i Work on? :-D

I'm not too much faster than you but my edges seem to be much faster so I would go with that.

Definitely edge pairing, especially first eight. Ideally for 5x5, your 12 edges combined should be only a little bit slower than your centers. I average about 35 for all centers and 45-50 for all 12 edges, and I think my edges are still slow comparatively. It's hard to get used to finding all those pieces all over the place, but I like to use a trick from one of Kevin Hays' videos, where he says to put your first 4 edges onto the D layer, so that you know you don't have to look on the D layer anymore. It helps your next 4 go a lot faster, in my opinion.

Ok thx for the help. Ill work on the edgepairing now :-D

What should my splits be for sub-2:10 reduction on 6x6? (Just centers and edges)

F2C: 25
L4C: 35
F8E: 50-55
L4E: 15-20

Those are atleast my splits, I have a sub2:10 redux
L4E:
