really weird solution (even for me) for Weekly FMC

Spoiler

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

B' (R' D F) // EO
(R2 U' R') // 2 squares
R2 U2 F2 // 2x2x3
(D' L D) // all but 6 pieces

B' R2 # U2 F2 D' L' D R @ U R2 F' D' R

@ = R' D R D2 L' R' D R D' L D2 // 2c2e ZBLL alg to leave 3 edges
# = [R2, S'] // edge cycle

Final solution: B2 F D2 F' B U2 F2 D' L' D2 R D2 R' L' D R D' L D2 U R2 F' D' R (24)


btw my Weekly FMC avg12 is at 24.90 now

L U' R2 //2x2x2
U B D2 U' B2 //2x2x3
L2 F' D F L' D2 L2 //F2L-1

So I found this nice start and ended up with a 39 move solution (random last slots, short OLL, U perm with cancellations).

Anyone sees something promising?

You can get to last 4 corners like this: L D2 L' D' L' F L F' (notice the first move cancels with your part of the solution). Insertion finder says you can get 29 moves with that.

However, I also noticed that you could solve the same F2L-1 in fewer moves like this:
L U' R2//2x2x2
L2 D' B' D' B2//2x2x3
B D' B' L D2 L//F2L-1

and continue to L4C with:
L D L' D F' D F D//L4C

which saves two moves over the other solution. Always look for different ways to put together the same blocks!

Thanks a lot! I was so stuck with the idea of inserting the last F2L pair while somehow solving the edges that I didn't think of just solving an LL block and inserting a lonely edge instead of a pair. I will think of this in future attempts.

L U' R2 // 2x2x2
U B U' D2 B2 // 2x2x3
B' L' B // F2L - 1
D' B' U' L' U L2 B L' D F' D F @ D' // to L3C
@ = [F', D B D']

Final solution: L U' R2 U B U' D2 B L' B D' B' U' L' U L2 B L' D F' D2 B D' F D B' D2 (27)

edit:
L U' R2 // 2x2x2
U B U' D2 B2 // 2x2x3
B' L' B // F2L - 1
D' (D') // shift
(L2 B' L' B) // square + form F2L pair
(L' B' U2 F U' B' U F' U2 B2) // WV to LL skip

Final solution: L U' R2 U B U' D2 B L' B D' B2 U2 F U' B U F' U2 B L B' L B L2 D (26)

L3C in your first solve is difficult for me to follow and NISS is still obscure to me and I don't know WV algs. I guess from this I just take a reminder to really examine all possibilities to extend the blocks because I probably had a white bias.

L U' R2 U B D2 U' B2 L2 F' D F L' D2 B D B' D' L' D2 L' D' (22)

L U' R2 //2x2x2
U B D2 U' B2 //2x2x3
L2 F' D F L' D2 L2 //F2L-1
L // Pseudo F2L
L B D B' D' L' D2 //LL
L' D' //Undo Pseudo

Proud that the best solution uses exactly my way of blockbuilding.
I think this is the most lucky solver I've ever encountered.
And it helps me to understand pseudo stuff.

found a 23 for the Weekly FMC using my 24 start

Spoiler

B' (R' D F) // EO
(R2 U' R') // two squares
R2 U2 F2 // 2x2x3 + EO + blocks

B' R2 U2 F2 @ D' L' D2 L' D' L D' R U R2 F' D' R

B' R2 U2 F' B' L2 B % F' D L' D2 L' D' L D' R U R2 F' D' R

Hey everyone, this is the FMC scramble from Hessen Open:
R' U' F L2 F D2 B' L2 B' L2 B' D2 U2 R' U2 L2 F2 U' R' B' D F' L' U' R' U' F
inverse:
F' U R U L F D' B R U F2 L2 U2 R U2 D2 B L2 B L2 B D2 F' L2 F' U R

And a very promising start:
R2 B' U L (extra move in the totally obvious 2x2x2: R2 U L)
switch:
R' B' U' R2 - F2L-1 in 8 Moves, if you switch again you get a free pair

My Solution was:
another switch:
R U' B U' B' U' for 5 Corners in 14 moves (sadly just 5 moves cancellation)
-> 25 move solution. I know Jan found another 25 with this start, but is anyone able to find a better solution?

Also a funny start:
R2 B' U L U R2 U B R - F2L-1 in 9 Moves + freepair

Would be nice if you guys try it!

Coming back from the Swedish Decathlon Challenge got me thinking that it might be a good idea to get some earmuffs or whatnot. This is because that especially during the first attempt there was a bunch of pretty loud kids in the same room, as well as organizational staff chit-chatting behind the competitors. Of course I don't know for sure if I would do any better with the same scramble with no distractions whatsoever, but why have more distractions than necessary. I do know that a bunch of BLDers use some sort of ear protection to block out sound, but does any decent FMCers use them too?

I know that Emanuel Rheinert is doing it as well as I do

Nice, you wear glasses too right? Do you have any recommendations when taking that into account?

Not really.. For my overear-headphones I can't wear my glasses while using them, but for my earmuffs I have no problems wearing my glasses. I also don't think they are special earmuffs, just standard ones

24.7, is that UWR? Pretty damn good either way. I had problems with that scramble (encountered parity all the time), so I had to do a 2C2E insertion to not DNF. By the way, perhaps we shouldn't call both the Berkeley FMC and the forum competition "The weekly"?

Sébastien already got a 24.3 (with a 21.00 mean of 3)

Why spend four extra moves to go from a nice an well behaved 7 cycle to some messy 2+4 cycle? Leave 7 corners instead and try *=R' F' R B2 R' F R B2

I had this skeleton for the weekly comp. Didn't use it because a 3C3E in 16 was probably better.
I wanted to check it on IF, but apparently it can't do 4 insertions.

Does "if the number of insertions is more than 4" actually mean "if the number of insertions is 4 or more"?

Yes. Long long ago it supported for 4 insertions. Since it always cost too much time and resource on the server, I changed the maximum number of insertions to 3. But I forgot to change the text.

I've searched it for you manually here: http://mf.qiyuuu.com/cube/if/f658ca5f34c393539a1cc605c9dde939.cube

Thanks for the answer, and for searching it manually!

23 is surprising. Although I doubt I could have even gotten sub-27.
