Sweet mother of Moyu.... Did not see this coming. First Sub-20 single!

19.48s
F L B2 D2 R' U R F L2 B D2 B' D' L U' F L D R F' R' U' B' L D2

I tried to reconstruct, but cannot quite work out what I did during F2L. It is the correct scramble, as I remember cross R' L' D L2 D after z2 inspection, then having the green-orange F2L pair in front of me.

I think F2L was pretty much done like this:

F2L 1: R U' R' U y L' U L
F2L 2: L U' L' U' R U R'
F2L 3: R' U' R U' R' U' R
F2L 4: U L U L' U2 L U' L'

but that doesn't give me the same last layer case. Must have done some unnecessary move in there, or something, to give me a different case. LL had EP skip and CO was a sune.

 

[h2f]

Nice!

Full CN as in white/yellow on bottom and any other color as FB?

Yes. But of course when there's no any pair I start with green or blue. In other cases every edge with center or pair. I like bottom pairs.

@JanW Congrats, when did you switch to CFOP? I think you were using another method, right?

 

[JanW]

@muchacho Still doing the same CPEOLL->CO->EP approach for last layer, combining the last 2 as well for about 20 cases. And then there's lucky skips, like the EP skip in the solve mentioned above.

On a side note, had I done F2L as described above, I would have followed up with:

CPEO: (y') R' F R F' d' L' U L
CO&EP: (y') R' U2 R U R' U R

That sune case is easy to recognize from pairs front-left and left-back as the one solved with antisune from the back. It's the only sune case I solve with anything but the standard sune.

Still doing the same CPEOLL->CO->EP approach for last layer

What are the advantages of that?

 

[JanW]

@mark49152 No real advantages really, I think... The first last layer method I learned was EO-CP-CO-EP. Then I figured out how to combine EO and CP into one step for most cases and went online to look for algs for the remaining cases. That's when I found these forums. At that stage I knew this 3-look last layer approach, and switching to CFOP would require I start by learning full PLL, only to get another 3lll approach, which hasn't been appealing. The plan is to switch to ZZ at some point and learn PLL for 2lll.

Awesome @JanW! Mine was not that long ago I remember how awesome it felt!!

 

[mafergut]

@JanW: Congrats! It sure feels good!

Right now I have less time to cube so I have not been able to do all the weekly comp events I was doing until a couple weeks ago or so. My little time spreads too thin and I cannot improve at anything so, for some time I'm concentrating in just one or two events for several weeks in a row. At the moment I'm trying to get used to 3-2-3 pairing in Yau 4x4 and deciding whether to stick to L4C one at a time or change to half centers. For now the verdict seems to be to stick to one center at a time and change to 3-2-3. My times with 3-2-3 seem to be more regular but I don't seem to be as fast as when 6-2 goes smoothly. Of course I don't get also those horrible times I got when 6-2 went awry, so I think it's worth the change but I'm not expecting a sub-1:10 single anytime soon. I got a couple sub 1:30 today, which is not bad.

Sorry if I'm a bit more silent than usual but I'm trying to make the most out of my practice time and that means less time with you guys in the forums.

 

[newtonbase]

Of course I don't get also those horrible times I got when 6-2 went awry,

There's the benefit of 3-2-3. It's consistently good where 6-2 is great when it works but it often doesn't.
I'm still undecided on half centres as I'm struggling to get decent times but I'm sure it's good when used properly. There isn't enough about it on YouTube and I don't have time to figure it out. I've done one 4x4 solve today with a 7 hour break between L4C and last cross edge.

 

[tiramisu]

Hi man. If you want to get into 3bld look at Noah's tutorial on Cubing World

Thanks will do.

 

[h2f]

I've finished ao100 on 6x6. It took me 15 days. I did more than 100 solves - some in car waiting for wife, some in garden etc. I need to work 5x5 to get better with Hoya and some cases on last four edges.

I've finished ao100 on 6x6. It took me 15 days.

I just ordered my first 6x6. I'll get it Monday or Tuesday, then I think I'll be doing this. Your 6x6 times look remarkably similar to my current 5x5 times, so I'll probably be slower, but this is a good benchmark to beat.

 

[h2f]

Yes. Doing 6x6 helps 5x5 and vice versa - there are similar stages like pairing last four edges or building cross edges with Hoya. And I've finished ao100 with Roux CN and full CMLL - 29.23. In a last 20 solves there was a remarkable progress.

 

[muchacho]

How many algs have you learned (or relearned) since you are practicing Roux again?

I have a 7x7 but not a 6x6, I am scared of pops since I saw Selkie's video.

 

[h2f]

Let's count. I knew all basics algs plus niklas, antiniklas d2, d3, d4, b2, c4, h4 (it's obvious) e3, e5, e1, f1, f3 = 19. 42 - 19 = 23. But this is not exact number though I had to relearn recognition patterns. I remembered only few no more than 10. It was relearning process so it came quickly - usually I need much more time to learn new things. Still few algs are hard to execute and recognize, for example I need few seconds to recon what case of T shape there is. In next week I'm gonna to focus on SB special cases.

 

[muchacho]

That's fast even if you knew them before.

 

[mark49152]

Yes. Doing 6x6 helps 5x5 and vice versa

I agree with that in theory, but my personal experience is different. 5x5 helps 4x4 helps 3x3 for sure, but I find 6x6 different because it's a bigger and clumsier cube to handle. I cannot turn as fast and have to take much more care not to misalign it. Then when I go back to 5x5 I find I'm not pushing speed as much because I've adapted to slower turning.

Perhaps with a lot more practice it might be different though.

I think we both may have right - my times in 5x5 are a little better though I've done 120 solves in last four months and it's the same number I've done on 6x6 in last 2 weeks. For example I've done pb on 5x5. I think it helps due to fact that doing 6x6 makes you familiar with stages of solves on 5x5. Of course if you do it with the same method.

 

[mark49152]

I think it helps due to fact that doing 6x6 makes you familiar with stages of solves on 5x5.

Yeah undoubtedly if you're still learning on both, whichever you practise first helps the second. My comment was about the situation where you're familiar and competent with both, and just trying to get faster.

Of course with 6x6 there's more going on and that combined with the more awkward cube does create the feeling that 5x5 is simpler and easier when you go back to it. That sometimes helps too.

 

[h2f]

Yeah. I've noticed that some experienced cubers solve 4x4 or 5x5 before their attempt on 3x3.
