Thanks CubeNovice and Cuberoots. Let me show you..

Warming, MustCube 451 OnGoing

Spoiler:

MustCube 451: L' F2 U R2 F2 U D' B' U' L D2 U' F2 R2 B R' D2 L R D2 U' B U' F2 U2 R' U' F R' L

pre move R'

L2 U L' R U' Pseudo 2 X 2 X 2
D2 B L' U B' U' Huh.. looks good
R D' R' D B Ahh only these two freaking egdes..

CubeNovice , can you explain a little further how J-perm can be of use? Oh wait... I think I get it. When I sticker the four egdes, I could find them earlier in the solve and then ... no .. I don't get it. How is the J-perm (no two edges swap) going to help?

oooh Marcel!

T-perm swaps opposite edges (and two corners)
J-perms swaps adjecent edges (and two corners)

For inserting the edge swap you would sticker the two edges and (in this particular case) the one corner that is solved.
You can now go trough your solution and find a place where you have the edges opposite (insert optimal T perm or the alg I posted) or adjecent (insert optimal J-perm). In you particular case you want to make sure that the stickered corner is not involved in the swapping alg: you do not want to "unsolve" it.

BTW your skeleton also has two corners twisted in place so you still have a lot to solve!
but you have two swapped corners in there so with a little luck the right T-perm or J-perm you can solve four pieces at one time.

Cheers

LOL, I am sorry about that. I guess my 40 - 50 move solutions is not going to help you FMC-gods anything.. LOL Thanks for the explanation.. I am going to do just that now..

no worries

BTW in your skeleton you can swap the edges AND solve two corners with the u2 alg I posted
But it needs one set up move so it takes you 12 moves...

Ah.. and all the way at the end you can use it to swap the two twisted corners in 10 moves thx to a cancellation on D

Yeah thanks, but I found that one out myself with a different alg. R2 U' R2 D B2 L2 U L2 D' B2

why uise a T-perm if you can use a cooler alg

[CubeRoots]

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

ooooh just looked, lots of nice starts there will try tomorow

[Sebastien]

congrats on the 23 you got (and the 25) http://cubecomps.com/live.php?cid=201&cat=15&rnd=1

could you share the scramble?

Wow Sebastien, 23 moves is great!
Do you have the scramble for us?
Gus

Thanks! I'm very happy to have eventually beaten my official PB of 24 that I set 2.5 years ago when I was by far worse in FMC than nowadays. Also now I'm 2nd in Germany again!

Scrambles and my solutions from this weekend:

1st attempt: B L2 R2 D2 U2 F' U2 F' R F2 D R' U' L U' L2 F2 U2 L2

Lösung: 25 moves

Spoiler:

Premove: B'
2x2x2: R' D2 R U2
More blocks: U' R U
switch and L4C: B R' F' D F R2 F' R' F R D' F D'

Skeleton: R' D2 R U R U D F' * D R' F' R F R2 F' D' F # R B'

No great start, but great cancelations (optimal):

* = F D' B' D F' D' B D (5 Move)
# = F' R B R' F R B' R' (5 Move)

Solution: R' D2 R U R U B' D F' D' B D2 R' F' R F R2 F' D' R B R' F R B2

25 moves.

2nd attempt: D2 L' D2 R' D2 U2 R D2 F' U' F' D B2 D' F' L2 R' B' U2

Lösung: 23 moves

Spoiler:

2x2x3 on Inverse: B2 R' F' D B
F2L-1: F2 D' F
More Blocks: F D2 F'
switch and L3C: D F D' F' D R' D' R D'

Skeleton: D F D' F' D R' D' R D' F D2 F2 D F2 B' * D' F R B2

* = F2 D' B' D F2 D' B D gives 4 move Cancelation (optimal)

Solution: D F D' F' D R' D' R D' F D2 F2 D B' D' B' D F2 D' B F R B2

23 moves.

I had the solution afters 10-15 minutes. So many possibilities and great beginnings! I couldn't do better though within one hour. I'm curious if someone finds a better solution for this scramble!

3rd attempt: F2 R2 B2 F D2 L2 D2 F' R2 D' R' F' D F U' R2 B U' L2 U

Lösung: 30 moves

Spoiler:

Premoves: U'
Pseudo-2x2x3: D L D' L2 B2 L'
More blocks: D2 R D' R2
switch und F2L-1: U B R' D' R'
L3C: D F D' F D2 F2 D' F2 D' F2

Skeleton: D L D' L2 B2 L' D2 * R D' R2 F2 D F2 D F2 D2 F' D F' D' R D R B' U'

* = D2 L' U L D2 L' U' L

Solution: D L D' L2 B2 L2 U L D2 L' U' L R D' R2 F2 D F2 D F2 D2 F' D F' D' R D R B' U'

30 moves.

Bad attempt, especially seen the decent start. I was probably too exhausted that Sunday morning to be fully concentrated. The fact that I just found a 28 move solution with block-commutator finish only while writing this solution down is confirm this. But...whatever!

Mean of 3: 25, 23, 30 = 26.0

After getting the 23 I had the following average of 12 out of official attempts:

26, 26, 27, 27, 27, 26, 26, 30, (DNF), 28, 25, (23) = 26.8

Sub 27! I really doubt that I will be able to do that again.

[irontwig]

My 28 was imo pretty boring, so I think I'll post my weird 3-edge skeleton for the third scramble:

D' R' U' L2 [2x2x2]

Switch to inverse:

U B2 R U2 R2 L' B2 L [Pseudo F2L-edge]
L' D L D' B' D' B D [Putting corners in the 6 move case]
D' B' D' R D R' B D B' R' [Leaving three edges]

This gives a 23 move skeleton: D' R' U' L2 R B D' B' R*D' R' D2 B D L' D' B2 L R2 U2 R'.B2 U'

Due to a shortage of time, nerves and experience with edges insertions the best I could find was .= R U' R U D' F' U F U' D, while IF suggests *=R D R' L B' R' B R L' D', which is just one move better for 31.
