WR-potential scramble from Sapporo Open 2014.

Scramble: U2 F2 U2 F' L2 U2 B' U2 B' D' R D B R' U2 F2 D' F2

My 21 move solution. (It is same as jpbrc's but I didn't copy.) Why didn't I get this in a competition.

Spoiler

Solution- D U' R2 U' R' U R' U' D' F D2 B' D' F D B D' F2 R B L2

On Normal
D //2x2x1 [1/1]

On Inverse
Pre Scramble- U2 D'

L2 B' //2x2x3 [2/2]
R' F D' F' D //F2L-1 [5/7]
U R U' R U R2 U' //L3C [7/14]

Correction- U2 D [2-1/15]

Skeleton on Normal- D U' R2 U' R' U R' U' D' F D + F' R B L2

Insert at +- D B' D' F B B D' F' [8-2/21]

 

[Sebastien]

I just worked with a L5E skeleton for the first time ever, and it turned out to be really good.

(2nd scramble of the current German forum competition)

Spoiler

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

On Inverse:
EO: F B2 D B'
more blocks & CO: L2 D R' U R2
L5E: U' * F2 U F2 B2 D

* = U2 L' U2 L F2 B2 R' D2 R D2 B2 F2 (cool conjugate!)

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

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

24 moves.

The insertion finder says that 25 moves is optimal!

I'd like to learn FMC, and I've seen Heise method, but it looks a little complicated. What else are good methods?

 

[obelisk477]

Petrus, tripod, and a good understanding of commutators (block, edge, and corner) will get you started. The longer answer is that there aren't really any methods for FMC, but that's not particularly helpful.

A good tutorial can be found here.

29.7 FMC avg12 done over the course of 4 days. All done within an hour.

24, 28, 33, 25, 30, 36, 30, 29, 27, 30, DNF, 29

Counting 36 and 33 is annoying, but I wasn't really expecting myself to go 12 solves without a few bad ones. First 5 make a 27.6 avg5.

To do: look at all of these solutions after school.

 

[MennoniteCuber1]

I've been using Petrus for a bit and I hit about 50-60 moves(usually in the high 50s). I am learning COLL. Should I switch to tripod or something like that or practice more with Petrus?

Try not to fully stick with petrus. After you've finished the 2x2x3, blockbuild to F2L-1 (basically an XXXcross) and work from there.

I just worked with a L5E skeleton for the first time ever, and it turned out to be really good.

(2nd scramble of the current German forum competition)

Spoiler

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

On Inverse:
EO: F B2 D B'
more blocks & CO: L2 D R' U R2
L5E: U' * F2 U F2 B2 D

* = U2 L' U2 L F2 B2 R' D2 R D2 B2 F2 (cool conjugate!)

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

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

24 moves.

The insertion finder says that 25 moves is optimal!

Nice solution!
But starting with EO and ending with L5E doesn't sound logic to me.

First sub-30 Mo3 at home!

Many of these scrambles should match the ones in Jay's average of 12.

Do you think we can get sub 30 moves steadily without using any techniques of commutators or insertions?

I do my FMC attempts without using any techniques of commutators or insertions.

I only use premoves and NISS, and I just try to force OLL or PLL skip, these skills easily enable me to get sub 40 moves.

But I thought these skips stuffs couldn't let me get steadily sub 30 moves, seems there is a restriction if not using commutators or insertions.

Perhaps, but why would you? It's the worst mistake that you can make, and I've made it several times myself; do not restrict yourself!

Thanks. Yes, you are completely right, the finish was pure coincidence.

A ridiculously lucky 22-moves solve (18 STM!). Scramble taken from this online competition.

I asked Baiqiang if he could add an option to the insertion finder, making it possible to restrict it to pure commutators as before the update several months ago. he implemented it today already.

I just added mean of 3 support to the weekly FMC. If you have any small suggestions that you'd like to see implemented over the weekend I'll get to as many as I can in celebration of FMC USA this weekend!
