SSC (Shadowslice Snow Columns) 3x3x3 Method

[Teoidus]

I'm not sure ending with PLL is that great, and it seems like crafto's method (EObelt+CO, rouxblocks, CP+ULUR, Mperm) is going to be more efficient, anyway. Usually when reducing to an LSE like state solving the F2L and doing PLL is just about the least efficient way to go about it

Okay here is an example solve of the latest variant of this method:

Scramble: R L2 B' L' B R2 D2 R' U' R2 B' L2 D' L2 U' R2 U D F2

z2 B L2 D' F R U2 L' // EOLine (7/7)
R' U2 // 1x1x2 + 1x1x3 (2/9)
R D2 // Setup for OL5C (2/11)
R2 D R // OL5C (3/14)
(U' D) R' // Belt + CO (2/16)
(U' D) M2 D' // First Pseudo-Roux Block (3/19)
M' U2 M U' R2 U' R2 U' R2 // Second Pseudo-Roux Block (9/28)
U' M' U2 M U2 M2 U' M2 U2 M2 (U D2) (11/39)

Btw, I didn't spend any time thinking about this solution, I simply did a solve then reconstructed it. The actual move count for this speed solve was, yes, 39. That's pretty cool. A sub-40 STM speedmethod is unheard of, this is on the same level as something like Heise.

But as far as I can see you got a CP skip in this solve, right?
The example solve I provided a few posts ago had 38 STM but I got an OL5C and FB skip too.

Yes but normally an alg of similar length would solve CP and ULUR so the movecount would be similar. Plus, my SB was really inefficient.

I don't think you can call it a sub-40 STM method because you got one sub-40 solve with it involving a skip.
That variation seems like a very cumbersome way to get to Roux LSE, why not just do Roux?
42 STM isn't unheard of, here's a reconstruction of literally the first solve I found when I searched "Alex Lau solve":

Scramble: B D L2 F L' D' L D' L2 F' U' R F2 R2 L' U2 R2 D2 R' B2
z2 D' B' M' B' r U R' F // FB
R U' R' U R2 U' R' U2 R' U' R U2 R' U' R // 2B
U' F R U R' U' F' // CMLL
U' M U' M' // EO
U M' U2 M' // UR and UL
U M U2 M' // L4E

what was the time for the solve?

You must be confusing me with someone else.

 

[Shiv3r]

I guess youre right, I was thinking about someone else on the "switching to a new method" thread.

Another example solve:

scramble: D2 L' U L2 B' L' F D' F' U R' B2 L2 B2 U2 F2 R' B2 U2 L'

z' //inspection
L B R D S //EO + line
D2 R D2 U2 //pair + triple
R' //OL5C skip
U D2 R' //CO + belt
D U' M2 U R2//FB
U' L2 U R2 D' R2 //SB
M2 R' U2 R U2 R' F R U R' U' R' F' R2 U //PLL
M2 //L4E skip

35 ATM, but 40 STM
I had a short EOline, an OL5C skip, average Roux blocks and an L4E skip.
Even with all the skips still not sub40.
Average movecount for OL5C is 4 moves, same for L4E so I guess that means a lot.

I want to see a fairly good solve with this method without any skips. I suspect it won't be near 40 moves.

 

[crafto22]

18.3x or something

First of all I got a CP skip, and the method I was describing wouldn't have a much higher movecount without a skip. Also, why are you considering STM rather than ATM? In terms of speedsolve execution 't that what matters? Also I am certain it would be near if not under 40 moves quite often. You yourself just got a 35 ATM solve. Even without the skips it would have been VERY close to sub-40 no doubt.

I think ATM is a fun metric to play with but STM tells more about actual speedsolving execution. Of course with training and decent fingertricks it's possible to execute something like (U' D) as one move but for something like (R2 M2 R'), which I actually used in my solve, it's not that easy. Technically R2 M2 can be performed as L2 but we want to avoid rotations and I believe the following PLL alg is faster with U turns instead of D turns.

The thing is that I have faith in your post-belt+orientation method anyway already. I just don't want to be too overhasty with my hype. Also my solves are generally not speedsolves, we have to keep that in mind. I will try to create more example solves and even if it turns out the average movecount will be around 41 moves it's pretty great.

EDIT: I'm stupid, R2 M2 can be performed as r2 of course and especially for a Roux speedsolver it will be quite easy to use such things in a real solve. No impact on my point though, I'd be curious to see R2 M2 R' being performed as one move.

 

[Shiv3r]

We should find out how fast that "speedsolve" was crafto.
I have a petrus/roux/L5E method that I can get around the same speed as my regular method(roux) when Im lucky. But I only use it when i have have a reaaaally easy 2x2x2 block. so the time would probably usually be horrible, but I only use it in the best cases.

so getting back on track, what is the average time for this roux-style method?

 

[Vexatious]

I still don't know how to CO

 

[Shiv3r]

MGLs CLS I algs are what I use.

I would likely do (r M'), using one of my Ring Fingers to flick the M-Slice.

Does this help?

There's basically the same thing on the wiki page

 

[wir3sandfir3s]

Someone should make a timeline on google sheets or something of the method development, that would be cool...
I would do it if I could focus and if I was good at actually following threads...

Do you use this as your main method? Does anyone?
