25 on the first scramble of FMC Americas, other attempts were bad so only a 28.67 mean but getting the best result on this scramble was nice

U (U' B U) // EO

Lots of pairs, but i chose to form one:

from here I couldnt find anything except a 22 to AB4C which IF gives 32 for
after 223 there is also a 14 move f2l-1 on inverse: (R' U2 R')

I found this using your start:

R' U' F D2 B2 L' F2 U2 L' R2 D2 R B2 F U F L' D' L' U' R' U2 R' U' F

F' L U R2 D F' // 222, 6

U2 B U' B' U B U B' U' R // L5C, 20

IF gives 29 cancelling first 5, then 2

finally got my first sub 30!

One of my favorite finishes I've ever done in an official FMC!

Fun 223 blockbuilding, took me a while to see that finish to 5C. Circled back to this later and found this with 20m left.

Spoiler: Attempt 3 (29): R' U' F L2 B2 L2 F2 D' L2 R2 D U' B L' F' L2 R2 D' B2 L' F U2 R' U' F

(L F R D') //EO (4/4)

Glad I wrote down this backup skeleton, didn't find anything else. Rough scramble for EO options, but blockbuilding was good, apparently. Wouldn't know for sure as I didn't check that. Japanese cubers there all teamed up post-attempt and found a 19 on someone's block start, but I don't have that.

Edit: Here's that 19.

Very nice! I think you meant to write D instead of D' as the 6th move...

Whoops! Thanks for noticing that, was trying to type this all up quickly before I got on the plane.

 

[asacuber]

Sorry for double post, but I did my first twisted corner inserton! Almost optimal too!

33 R' U' F D R F' B R U2 L' B R' D R2 U2 L2 U' L2 B2 R2 L2 D L2 R' U' F
F// Partial EO(first time trying this out as well :3)

B2 D' R' L' D L//223
D R2 D2 R2 D2 R2 D' R' D' R D'//AB3FC(this is actually 2 gen and i noticed this now :O Ill see whether there is a nice 2gen finish, help appreciated)
Skeleton: F U2 & B2 D' R' L' D * L D R2 D2 R2 D2 R2 D' R' D' R D' L2 F' U' R F2

insert at * : D R' D' L D R D' L' (8-6=2)
after that insert at &: R F R' B R F' R' B' (8-1=7) optimal is 6 for this

Final:
F U2 R F R' B R F' R' B D' R' L' D2 R' D' L D R' D2 R2 D2 R2 D' R' D' R D' L2 F' U' R F2 (33)
Someone give me a nice 2gen finish, I'm working on it too because as i said I saw this just now
also tips are appreciated!

New breakthrough in the theory of edge insertions (still under development)!

(sorry for the clickbait, but I have to put it in a spoiler because the competition is ongoing, and I don't want people to ignore it because of this)

Scramble (german forum weekly #3, ongoing): R' U' F U2 F2 D2 L2 U R2 B2 L' U' F' R U' R U2 R' F2 D' L U2 R' U' F

Spoiler

Skeleton by Tommaso Raposio and insertions by me.

R' U B' //EO 3/3
L F2 L2 B2 L U' //322+pairs 6/9
(L F2 L' F2) //3e3c 4/13

Here IF with "pure insertions" only gives 26, Tommaso (and IF with "other") found a 23.

But we can do better exploiting some "Corners First" techniques:

Skeleton: R' U B' L [1] F2 L2 B2 L U' F2 L F2 [2] [3] L'
[1] = M2 //From 3 edges to 4 edges (and skew centers) (yes, that's actually better) (1)
[2] = U M2 U' //Solve edges and centers (4)
[3] = U L D' L' U' L D L' //Corners (4)

22 moves

can someone please contact david adams regarding the weekly fmc

 

[NykoCuber1]

Do speedcube.de weekly , it's better !

Do speedcube.de weekly , it's better !

Ok, ill try that!

Edit: Just did an fmc attempt, got a crap 36
Afterwards i tried my start again and the first thing i got was a 32 ^_^

E: Someone help me: R' U' F L B F2 L2 F' D2 L2 R2 F U2 B' D F D2 F' D F' L' D' R' U' F

what my start was: L B R U F //EO
