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

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

U (U' B U) // EO
D2 L B2 R’ // 222 + pears
B' F' L2 @ B F D2 // F2L - 1
L' F L F' L2 // 19 to 3c

@ = [D, F U2 F']

Solution: U D2 L B2 R' B' F' L2 D F U2 F' D' F U2 B D2 L' F L F' L2 U' B' U (25)

Warning: Spoilers for this weekly comp
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-scr
Lots of pairs, but i chose to form one:
F'//pair
L U D F'//222
R' U' B D' R' D//223
U' R U2// F2L-1 at 14 :D

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')
help

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
U' L U2 L' // 223, 10
U2 B U' B' U B U B' U' R // L5C, 20

IF gives 29 cancelling first 5, then 2

My solutions from Hawaii 2018, 25.67 mean.

L' U F //EO (3/3)
L' F2 D //block+pair in a nice place (3/6)
R D2 R2 U' R' D2 R' //almost 223 (7/13)
B2 D2 L2 D' //2e2c (4/17)
D L' F2 R U' R' F2 L2 D' L' //done (7/24)

Final: L' U F L' F2 D R D2 R2 U' R' D2 R' B2 D2 L F2 R U' R' F2 L2 D' L' (24)

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

(F') //block (1/1)
(B2 L' F L2) //+block (4/5)
(U2 L2) //223 (2/7)
(D F2 L D L2 F' L F) //L5C (8/15)

Skeleton: F' L' F L2 D' (1) L' F2 D' L2 U2 L2 F' L B2 F

1: B L' F2 (2) L B' L' F2 L (cancel 4)
2: F' R2 F L F' R2 F L' (cancel 3)

Final: F' L' F L2 D' B L' F R2 F L F' R2 F B' L' D' L2 U2 L2 F' L B2 F (24)

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

(L F R D') //EO (4/4)
L' F U2 //222 (3/7)
R F' R F' R2 D2 //223 (6/13)
F R' F' R2 F R' F' //F2L-1 (7/20)
R F' R' F R //L3C (5/25)

Skeleton: L' F U2 R F' R F' R2 D2 F R' F' R2 F R' F' R F' R' F R D R' (1) F' L'

1: R' F' L2 F R F' L2 F (cancel 4)

Final: L' F U2 R F' R F' R2 D2 F R' F' R2 F R' F' R F' R' F R D R2 F' L2 F R F' L (29)

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...

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

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)
(F2 R' U F L2)U2// Complete EO+222
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)

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
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 :)

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
(L' B2 U2)//222
(L' D' L2 D2)D'//223

D' F' D2 F // 21 to 4c

F2 L2 F D L2 D2 L2 D' F' @ D' F' D2 F R2 U F D R F' U L'
@ = F D F' D F' D' F2 D' F2 D2 F D2 // 12 move ZBLL cancels 5

35, 28, 28 = 30.33 mo3 PR . Tied @Cale S on the last two!!!!!!!

Solve 1 was 20 to 4-twist, I inserted double hedge for 26 to 3E. Had 1 minute left so I just stuck U2 R U D' F2 U' D R U2 at the start.

Scramble 2: R' U' F U2 B2 U2 F2 L2 U2 R' F' D L B2 L D' L2 U' R' B' U2 R' U' F
D B // EO (2/2)
L2 U L2 // 123 (3/5)
D R U F2 D U' R U F2 D // 5C (10/15)

D B % L2 U L2 D ^ R U F2 D U' R U F2 D // 5C (15)
%: B2 L' U L B2 L' U' L // 3C (8-2/21)
^: D2 B U B' D2 B U' B' // (8-1/28, IF says 27 is optimal)

Final: D B' L' F L B2 L' F' L' U L2 D' B U B' D2 B U' B' R U F2 D U' R U F2 D (28)
Scramble 3: R' U' F D' U' F2 D' B2 D' R2 U2 L2 R2 F R U' B' L' B D2 B2 R2 D2 R' U' F
(L U' F R') // EO (4/4)
D' B' F D' // 222 (4/8)
U B U2 (U) // 223 (4/12)
(B2 U B U' L2) // 5C (5/17)

D' B' F & D' U B U2 L2 U B' U' B2 U' R F' U L' // 5C (17)
&: F U2 * F' D' F U2 F' D // 3C (8-3/22)
*: L2 F' R' F L2 F' R F // (8-2/28, IF says it's optimal)

Final: D' B' F2 U2 L2 F' R' F L2 F' R D' F U2 F' U B U2 L2 U B' U' B2 U' R F' U L' (28)
