So I just got my FMC PB single

B' D2 B2 U2 F D2 L2 F' D2 B' D' B' U' R' U2 F L' U2 L' B'

B' D2 R' F' * U'//2x2x2 (5/5)

U' F U L' F'//multislot, F2L-1 (5/12)
switch to inverse,
L D L' D'//setup F2L pair
B' L' B//insert pair, OLL skip, U perm left

*=L2 U' D F2 U D'

5 moves cancel on a 6 move insertion, wth

Final: B' D2 R' F' L2 U' D F' U' F U L' F' B' L B D L D' L' (20 moves!!!)


Well, time to never break my PB single again I guess

Edit (30 Sept 03:47)

Finished doing the scrambles from Canberra Spring 2016! 28, 26, 20 = 24.67 mean (just like Jay :D)

The 20 is the exact same as Jay's. Others who found the same solution were Mark Boyanowski, Walker Welch, and Ryan DeLine.

Moves in parentheses are on inverse.

1) R' U' F R B2 L2 R U2 R2 F2 R' B2 D' F2 L' R2 B' U2 R F' U2 R' U R' U' F

What I tried:

(B F2 L B')

Eventually went with this:
(U F' R' D B') // 222
(F2 L' U2 L') // 223
U2 L F U L' F' L U' L2 U2 L U' // 21 to 3C

3) R' U' F D2 R2 D L2 R2 F2 R2 D' L U2 L U' B2 F R U' B2 R U2 R' U' F
15-minute back-up skeleton:

What I went with:

My solution for this week's Berkeley FMC (I got the "you have already submitted a solution" bug).
Scramble: R2 U' F2 D2 R' F2 B R2 D B U L R' F D2 L2 U2 F D2 B2
Solution: U F R' L' F2 D' R L D R D' L' D R B U L' F2 L B2 L' F2 L R2 B U D (27 HTM)

On normal, premove D
U F R' L' F2 //2x2x2 (5+1/6)
D' R * D //2x2x3 (3/9)
R2 B U + B2 R2 B U //All but 5 corners (7/16)

* = L D R D' L' D R' D'
+ = L' F2 L B2 L' F2 L B2

The last step is just EO with an R2 at the beginning to save the pair.
 
Super neat insertion I found on this week's scramble.
Scramble: R2 U' L D F' L D2 U' R' B' L2 U' L R F' B' D2 F2 L2 R2
Inverse: R2 L2 F2 D2 B F R' L' U L2 B R U D2 L' F D' L' U R2

F U F2 L //2x2
(U' R2 U' R' F2) //2x2x3
F' B U' F B' //EO 4 edges + 2x2x1
R U2 F' U' F R2 //EO + 2x2x1
(B U B') //L3C
(R D R' U R D' R' U F' D2 F U' F' D2 F) //Backup

Backup: F U F2 L F' B U' F B' R U2 F' U' F R2 F' D2 F U F' D2 F U' R D R' U' R D' R' B U' B' F2 R U R2 U (38)

Skeleton: F U F2 L F' B U' F B' R U2 F' U' F R2 U' B U' B' F2 R U R2 U (24)

Insertion 1:
F U F2 L F' B U' F B' R U2 F' U' F R2 U' B U' B' F2 R U (U2 R D R' U2 R D' R') R2 U 24+8-2=30
Skeleton 2: F U F2 L F' B U' F B' R U2 F' U' F R2 U' B U' B' F2 R U' R D R' U2 R D' R U (30)
Backup 2: F U F2 L F' B U' F B' R U2 F' U' F R2 U' B U' B' F2 R U' R D R' U2 R D' R U F' U B U' F U B' U' (38) (making up backup solves all the time is gr8)

Insertion 2:
F U F2 L F' B U' F B' R U2 F' U' F R2 U' B U' B' F2 R U' R D R' U2 R D' (U L U') R U (L') 30+4=34!

Final solve: F U F2 L F' B U' F B' R U2 F' U' F R2 U' B U' B' F2 R U' R D R' U2 R D' U L U' R U L' (34)

The last insertion was the weirdest thing that happened to me in FMC since I started FMCing.
F U F2 L F' B U' F B' R U2 F' U' F R2 U' B U' B' F2 R U' R D R' U2 R D' * R U
When I was at * trying to find the 2nd insertion, I found out that it was a commutator that had been started already.
I mean, if you perform the moves R U at *, it's a niklas. And it had already been started (weirdly though).
So, what I did, I inserted the corner that was at UFL at * with U L U', then the rest was just straightforward. In addition, the moves needed were the final moves of the skeleton (plus an obvious L')!
So, it was sort of a quadruple cancellation, but not quite.
Happy with the ending.
The 1st insertion was really hard. I mean, I couldn't find any good one.
The 2nd one was magical instead.
IF gives 32 for 3-cycles and 30 for 2*2-cycle.

Edit:
My solution for this week's Berkeley FMC (I got the "you have already submitted a solution" bug).
Scramble: R2 U' F2 D2 R' F2 B R2 D B U L R' F D2 L2 U2 F D2 B2
Solution: U F R' L' F2 D' R L D R D' L' D R B U L' F2 L B2 L' F2 L R2 B U D (27 HTM)

On normal, premove D
U F R' L' F2 //2x2x2 (5+1/6)
D' R * D //2x2x3 (3/9)
R2 B U + B2 R2 B U //All but 5 corners (7/16)

* = L D R D' L' D R' D'
+ = L' F2 L B2 L' F2 L B2

The last step is just EO with an R2 at the beginning to save the pair.

Why did you choose D as a premove? Based on what? I can't see it. Thanks

It's needed for the first block.
I have found it before solving the block actually, just trying random stuff at the beginning of the inverse scramble. D' makes a nice pair close to two "good" edges (i.e. correctly placed closed to their matching center).

I see. I'll try this 'technique' and see if I get better results with it :) Thanks
Also, the last step was pure luck or did you expect the edges to end up solved?

Edit:
This is my entry for Weekly Competition 2016-40
I've found a similar insertion to my solve posted before on this same thread.
--------------------------------------------------------------
Scramble: U F' L' F D' R' D B U R2 U2 L B2 U2 B2 L' D2 B2 L' B2

Skeleton: F' R' U2 L2 U' R2 U2 R' D2 F U F' L' U2 D' L2 U L2 U' L2 D L' U' L' U L2 U2 (27) (I don't know the 3-corner-twist alg :S)

Backup solve: F' R' U2 L2 U' R2 U2 R' D2 F U F' L' U2 D' L2 U L2 U' L2 D L' U' L' U L2 U2 (U2 R' D R U2 R' D' R) (D' B D F2 D' B' D F2) (41)

Insertion 1:

Backup 2: F' R' U2 L2 U' R D' R U2 R' D' F U F' L' U2 D' L2 U L2 U' L2 D L' U' L' U L2 U2 D' B D F2 D' B' D F2 (37)

Both yield to a 35-move final solve, one having 2 cancellations, the other having a weird insertion technique I've been getting a lot lately.
This technique is actually not a technique, but somehow having a bit of luck. Near the end of the solve, you find an already started insertion.
F' R' U2 L2 U' R D' R U2 R' D' F U F' L' U2 D' L2 U L2 U' L2 D L' U' L' U * L2 U2
See, at *, if you do L2, it's a 3-cycle "with premove U2". Then what I do, is insert the URF corner in ULB, "undo the L2" (that actually I've never performed), undo the insertion, and then undo the "premove".
All the things that are "quoted" are because the solve does it by itself. You can see that the L2 move and the U2 move are already part of the skeleton, I just inserted the corner insertion and undoing.

Final solve: F' R' U2 L2 U' R D' R U2 R' D' F U F' L' U2 D' L2 U L2 U' L2 D L' U' L' U B' R B L2 B' R' B U2 (35)
Insertions are optimal :)
Found in 58 minutes!

Any sort of advice is welcome, thanks

now the state of the cube is symmetric...

I then did D' F B D' B' D F2 D' F D to get 19 to 3 corners, 24 after insertion

The solution I found before this was a 23:

Weekly scramble for David Adams' Weekly Competition:

Backup solve: R F2 D' R F' D2 R2 D' R D R' U2 D2 D B' E2 B D' B' E2 B F' R F L2 F' R' F L2 (31)

Edge insertion:
R F2 D' R F' D2 R2 D' (D L' E' L D' L' E L) R D R' U2 D2 (13+10-2 = 21)
Skeleton: R F2 D' R F' D2 R2 L' E' L D' L' E L R D R' U2 D2, converted:

(the initial skeleton is shorter than the total moves required for both insertions, lol)

Even though this solve is very good, I feel like I could have found a much better one.
I mean, there was a pseudo 2x2 at the beginning of the solve!
The 1st place of this week must have found a sub-20 solve xD
IF gives 25 moves.
 
cool insertion for Weekly FMC

24 move solution

I also found a 23
 
I got an official 25, 28, 23 = 25.33 mean at German Nationals, making me national champion! I am very happy with it, although a lot of luck was involved, especially with the second and third solves.

1st Scramble: R' U' F U2 B2 F L2 B' U2 R2 U2 R2 B F' D R' D R2 B U2 R F L' D' R' U' F

On Inverse: R' D' R // 1x2x2
Switch, L' D' B2 D' F' D' // 2x2x3 + blocks
B L' B2 U2 B L2 U' // 2 flipped edges and three twisted corners
Skeleton: L' D' B2 D' F' D' B L' B2 U2 B L2 U' R' D R
Finish: L' F' L2 D' L' D2 F' D' F2
Total: L' D' B2 D' F' D' B L' B2 U2 B L2 U' R' D R L' F' L2 D' L' D2 F' D' F2 (25)

The 2x2x3 start looked really promising. I actually found a 21 L3C finish first which also resulted in 25, but this one is a bit cooler. (Given that the skeleton perfectly sets up for the algorithm, it is almost a bit unlucky that it wasn't possible to cancel a move - had the skeleton ended with any U, L or F face move, it would have canceled at least one move.)

2nd Scramble: R' U' F R F2 U2 B2 R U2 L2 R F2 R B' U L' B L F D' L2 D' L' B2 R' U' F

On Inverse: U2 B' // 1x2x2
Switch, U R' U2 // 2x2x2
Switch, F L F' L2 F // 2x2x3

Not a very easy scramble. This was my backup solution: I didn't find anything on the 2x2x3 right away, so I wanted to switch so I solved it using CFOP, which actually led to a 24 move L3C skeleton by chance. 4 move cancel was quite lucky as well. I went on trying out different 4 move EOs on the inverse scramble, some of which looked promising, but couldn't find any finishes.

3rd Scramble: R' U' F U' R2 D2 F2 L2 R2 D2 B2 D' F' D2 L R2 U' L2 D' U2 B' F' U' R' U' F

On Inverse: F2 B D' R' U2 // 2x2x3
F' D F' D F D2 F D' F' L D2 L' // CFOP F2L
B' L' D' L D B // Finish
Total: B' D' L' D L B L D2 L' F D F' D2 F' D' F D' F U2 R D B' F2 (23)

Really cool scramble - three blocks already made. I found the lucky 2x2x3 in five minutes, but only found the lucky finish after trying some more logical continuations.
 
I beat my official pb single by 7 moves at German Nationals.

Scramble: R' U' F U' R2 D2 F2 L2 R2 D2 B2 D' F' D2 L R2 U' L2 D' U2 B' F' U' R' U' F

(F2 B D' R' U2) //2x2x3 (5/5)
(F' L' F L) F //F2L-1 (5/10)
(L D L' D F' D2 F D') //to L4C (8-1/17)

Skeleton: F D F' @ D2 F D' L D' L2 F' L F U2 R D B' # F2 (17 moves)

@ = [B U B', D2]
# = [B' U2 B, D']

Solution: F D F' B U B' D2 B U' B' F D' L D' L2 F' L F U2 R D B2 U2 B D' B' U2 B D F2 (30 moves, cancelled 3)

Unfortunately IF tells me I could have had a 26 with my skeleton.
I found my skeleton after 15 minutes and started trying out insertions after 20 minutes. I have never done a 4C insertion that is a twisted 2-2-swap like that before and I was clueless how to be efficient and in the end I just took the first insertion that cancelled at least something.
Anyone tips for that kind of insertion?
