Any more roux?

[5BLD]

the sixth person to do that with Roux?

I think there's more than five who can sub-15.
Let's see who gets to sub-15 first out of us two!

Ok, I am praying that I am not asking something silly, or that has been asked before...
Are there any extra little bits to add to the awesome but simple method that is roux? Like in fridrich, you can 'add on' MGLS, WV, VH, ZB etc. Little variations of the method. Can you somehow influence the second block during the first block? Or even influence both before even starting the blocks? Forcing CMLL skips during blocks? Combining steps? I am by no means an expert at all, but I have been experimenting and I find that making some premoves before the blocks is somewhat useful for reducing move count although it's not particularly practical(long inspection).

Additionally, I came up with WV for Petrus, not Fridrich.

Hm, but why R of L/R flipped? To achieve this state, you would use the same methods as the regular 4b. And 4a+4b are almost fused... And 4c is instant recognition... I'll have a go though...
Your algorithms use a bit too much M U for me... Because, to do an M U I have to use my right index for M then jump over to U.
I think I could only apply this where it would be more effiecient to do so.

I chose R of L/R to be flipped to accommodate for the UF flipped set. You can convert all of the cases to ones that only use moves in the RUM subset by doing x or x'. This was just an ergonomic choice for me.

I don't see too much wrong with flipping L instead, mirroring the algorithms (or using some other preferred algorithms).

I don't know if my system would really save time or moves, as I haven't calculated the average move count. It's just a different approach.

The use of MU for roux is almost as imperative as being able to blockbuild effectively. If you optimize l6e, this is the easiest way to gain speed other than 1 look corners imho. I still suck at f2b and I know only a few cmll and I can sub 25 consistantly. Roux is cool in he fact that you can use qqtimer for MU scrambles and practice l6e. During inspection I can spam l6e in a matter of seconds... the transition is awkward into l6e for me, but M2 with a small pause I can spam the last part. I just takes a bit of practice.

 

[5BLD]

@maggot: No no no I meant literally M U. As in the two moves M and U.
These are my fingertricks:
M right index
M' left ring
U right index
U' left index
M2 left ring followed by right ring.
So therefore repeatedly spamming M U is difficult as I have to constantly hop across with my right ring finger.
Of course I can moo decently, although not nearly as good as waffo, cool frog, or kirjava. I'm almost sub-20. I average 21.
Sorry for the confusion.

During inspection, I can spam l6e in a matter of seconds

Hey, no twisting the cube during inspection!

M2, and a short pause

Ok, on a more serious note than my last sentence, here is a little tip which I only discovered last week. To look for misoriented edges, simply look on the F face for the U/D colour. Or have a quick glance underneath. No need for an M2.


@cubacca:
This would actually work! I am choosing not to incorporate this though, because I actually do 4a and 4b in a smooth motion, using shortcuts which I have picked up. I think my first block and CMLL recognition needs work, but that's what I'm going to ask now.

My split is 5-5-4-6 on average, or on a good day, 4-4-4-6.
What do I need to work on?

 

[oll+phase+sync]

Lately I dicoverd that I'm able to execute M2 by just using one finger one move. But in many cases I "loose contorl" of the cube when doing this. Any observations/suggestions?

An other very special CMLL+EO subcase: M'UM' + COLL
Don't get this wrong, I don't want to do EO before corners. I just wonder, if I spot an easy 3 or 4 move EO case is it worth it in that case

 

[Kirjava]

Better to do corners first. You can use CMLL and force the easy case anyway and still do the 3 mover without wasting moves on COLL. COLL is only really useful when you already have an EO skip before CMLL.

 

[5BLD]

Oll+phase+sync:
Well that won't really work in my opinion because you will have to flick very hard. But maybe your fingers are stronger than mine! I do an M2 with my left ring followed by middle, or at least I try to. It will be more efficient than left ring-right ring.

As for EO then COLL for the M' U M' cases, I don't think it is worth doing so as CMLL has shorter cases but, yes, mess up orientation. (But something like doing the first move of sune as r instead of R is useful if you understand the cases. )
Since this can only be good with COLL-CMLL mutual cases, like sune, you would end up doing EO->CMLL instead of CMLl->EO which would mean L/R edges will be very hard to look ahead for.
And won't give you anything extra.
I orient the centers during CMLL though as all it is is making an R an r or adding an M move in between where appropriate. This gives me the extra fraction of a second to look ahead for EO cases.

 

[Kirjava]

I orient centres at the end of the second block. Costs 0 extra moves. After this CLL+EO is essentially 1look. It's really worth learning how each CMLL affects EO if you want to 1look it. You should be able to predict the what the EO will after CLL before you even perform the alg. After you get used to this you can start adding an M' or w/e before CLL to change the resulting EO case into a much better one since you know what the result will be. Or just use an alg you know to solve CLL+EO in one go

Since you're recognising CLL and EO at the same time, while you're executing that 2 or 1 algs as a single set of moves you can find the L+R edges for a nice transition into the next step. Then you just have to perm everything and force any skips you can.

Basically, you shouldn't need any kind of pauses after you start CLL.

 

[5BLD]

Ah thanks kirjava, I'm going to try it. I only just finished learning full cmll... I will look at each algorithm in depth.
Yeah you do cmll and eo in one alg don't you? I might try that too, at least for the ones where I can just add Ms.

 

[uberCuber]

To help with your M U problem, try pushing upward on the DB sticker with your left middle/ring

See push.
M U can be fast.

 

[5BLD]

Argh, you got a Lubix Guhong! I have not got access to good cubes...
Hm... I should try that. I use my right index for M right now- what you do seems awkward, but all it needs is practice i guess...
Thanks, ubercuber and Stachu! It'll make my M slice perm alot faster.
Do you recommend a left ring-middle for M2? or should i carry on doing it right ring-left ring/ left ring-right ring?

 

[uberCuber]

I do it left ring-middle, doing with both hands feels awkward to me

 

[5BLD]

Hm, i think i will stick with left-right, because now with the push DB, i no longer need to jump over with my right index. It is very awkward for me, but i'll practice it.

 

[StachuK1992]

I do:
U: right pointer
U2: double-trigger right pointer&middle
U': left pointer or right pointer back-flick

M': left ring BD to DF
M2: Just 2 M's
M: left ring DB to BU

So basically left hand for Ms, right hand for Us

Also, pay attention to how I hold my cube. My hands are closer together.

 

[5BLD]

M2 just 2 M's? Isn't that a bit slow?
Yes, your hands are closer together than mine are usually. Probably to do with small hands, and having to reach both M and U with both hands. But with this new strategy I won't need to do so anymore.

 

[StachuK1992]

My M2s often depend on teh alg.
For my Zperm, I double trigger pinky and ring fingers, but for other algs, (pure adj flip) I just do 2 M's. It really depends where my fingers are.

 

[Cool Frog]

Any help in optimization of LSE?
I know you can influence where the Opposite edges are after EO with how you finish EO.
I have also figured out how to solve all the EO cases in 7 moves or less (Besides superflip).

Would it be worth (intuitivly) learn the EP when the UL and UR edges are swapped?
