Not that great of a solve, but good for me because I found nearly optimal insertions in ~16 minutes :)

scramble: B' L' R2 D L F R' L U' B' L R2 D' U2 B' F2 D B2 L' R2 (David Adams 184)

(L' D' L U') // 1x2x3
B' F2 U F2 // pseudo 2x2x3
(F) // fix pseudo-ness
R2 U2 F L F' U2 R2 // EO
D2 B2 D2 // AB5C

skeleton: B' F2 U F2 R2 U2 F L F' * U2 R2 D2 B2 D2 F' U L' D L (19)
* [F D F', U2] - cancels 4

skeleton: B' F2 U F2 R2 U2 F L * D F' U2 F D' F' R2 D2 B2 D2 F' U L' D L (23)
* [L', D R' D'] - cancels 4

skeleton: B' F2 U F2 R2 U2 F D R' * D' L D R F' U2 F D' F' R2 D2 B2 D2 F' U L' D L (27)
* [R, B' L B] - cancels 2

final: B' F2 U F2 R2 U2 F D B' L B R' B' L' B D' L D R F' U2 F D' F' R2 D2 B2 D2 F' U L' D L (33)

IF says optimal was 32
 
My solutions from the final round of Only FMC 2017:

1st scramble: R' U' F R2 U2 R' F2 D2 F2 U2 F2 R' B' D' F' U' R2 F' U L' R U2 F' R' U' F
2*2x2x1: U2 L' F' R
Pseudo-F2L-1: D B U2 R2 D' F2
3E3C: D R B * R2 B' D2 F'

* = D' R2 D R D' R D R2 (Inverted Anti-sune)

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

23 moves.

Comment: Once more thanks to Guus for his remark on inserting Sunes at Eat Sleep Cube Repeat 2014! :D

2nd scramble: R' U' F L2 F2 D2 R2 D2 R2 B2 R2 U L2 D' B' L' F U2 R U B' U2 R D2 R' U' F
EO+2x2x1+pairs: R * U B L
2x2x2: F' U2

at this point I first switched and found the following L3C: F D2 B D2 B' D2 F' R2 F' R2 F U R2 U' R2

However, after putting the skeleton together, I noticed that I could get the same L3C in a slightly shorter way:

2x2x3 + many blocks: R2 U R2 U' B' D2
L3C: B2 R2 B R2 B' R2 B' R2

* = R' F L' F' R F L F'

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

26 moves.

Comment: I wouldn't be too surprised if someone finds a better finish for this start.

3rd scramble: R' U' F U2 F2 U2 R2 U2 L2 R2 U' L' F2 L' U L2 B R2 F2 U' L U' R' U' F
2*2x2x1: F2 U' L U2
2x2x3: (L' F2 R')
F2L-1: D2 R' B R2 L' D' L

I did the R2 to save the other 3 move pair so that R' D2 B' D' B would give F2L. I then noticed that the OLL would skip and saw, that I could also solve the last F2L pair differently to cancel into OLL:

F2L: F D' F' D2 R'
OLL+Skip: R D F D2 F' D' F D F' R'

Luckily, the end also cancels with the inverse part. :)

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

23 moves.

Comment: I guess this is what you could call "the lucky one". I certainly won't complain that everything cancelled so nicely. :D At this point in the solve, I already had a 25 (PB mean!!!) from a completely different start (giving L3C in 20), but this solution was definitely the ice on the cake. :)

23, 26, 23 = 24,00 mean of 3 :)

Huge congrats!
I wouldn't say the last one is very luck. Knowledge of LL algs and spotting the alternative last pair insertion that lead to the same OLL is not luck :) Cancelling 3 moves with premoves kinda is, but whatever.
I think the first one was luckier. Or do you think inserting a sune in 8-2=6 moves is normal? I did it recentely and I though inserting it in 7 or 8 moves was very lucky. Is there a special technique that Guus told you?
 
Thanks Sebastiano!

Well, you are definitely right, 6 moves for an inserted sune is definitely better than average, I would probably consider 9 as normal. :)

About Guus: No, and sorry if I made you curious. At that competition, I had a 27 with 3 edges and 3 twisted corners that I solved using a block-commutator and a corner commutator and we talked about that solution. So he asked me, why I didn't check if I could insert a sune, which I simply had forgotton about during this attempt. That just stuck in my mind and since, I always check for sune insertion in such cases and always have to think at Guus when actually inserting one. :D
 
I read most of @porkynator's book yesterday and learned a ton from it. Here's my first FMC solution with 2 insertions from this week's SS weekly comp:

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

(R B U) // EO
(L R' B' R B R') // A bunch of blocks
B' F L F L' B R F R' // To L4C

Skeleton (16): B' F L F * L' B R F B' R' B R L' U' B' R'

* = B' R2 B L B' R2 @ B L' (1 move canceled)
@ = R' B2 R F2 R' B2 R F2 (1 move canceled)

Solution (30): B' F L F B' R2 B L B' R B2 R F2 R' B2 R F2 B L2 B R F B' R' B R L' U' B' R'

Unfortunately I ran out of time, so I found the quickest insertions I could. IF found a few 25 move solutions that canceled 7 moves though. Really happy with my skeleton, but I definitely need to get faster at finding quick insertions.

Also, a question: I had a couple moves written down incorrectly that I changed within 10 seconds of time being up. Generally speaking, how strict are you guys with the hour time limit? At what point would you just consider it a DNF?

By the way, thanks @porkynator!! Your book is amazingly helpful! :)
 
This was for 2017-34, but I did the attempt after the results were posted.

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

Solution: All on Normal Scramble
D2 B U' D B' ||| 2X2X2
L' B' U2 B U' ||| Added a Roux block
F L2 U' ^ F U ||| Broke the Roux block slightly, but added a square to blue
F2 L' U' F2 U L2 D' L' D ||| Played around with blocks for AB3C

^ = U L2 U' R' U L2 U' R

Final Solution (28) = D2 B U' D B' L' B' U2 B U' F U' R' U L2 U' R F U F2 L' U' F2 U L2 D' L' D

Pretty good solve for me, and one of my more weird solutions.
I think this is like my 7th or 8th sub-30.
PB is still 27 lol.
 
Tied my PB single of 29 on a practice solve.

Normal: D B2 R2 F L2 B' L2 B' R2 B D2 B2 U' B' U' R U' L' R2 F R'

F B2 L' // 2 Heise Squares (3/3)
R' F U # F' U' // 3 Heise Squares (5/8)
R D R' D2 R2 D R D' B' // F2L-1 (9/17)
F D' F' D2 // AB3C (4/21)

Insert at #: U2 R2 U L' U R2 U' L U'

Final: F B2 L' R' F U' R2 U' L' U R2 U' L U' F' U' R D R' D2 R2 D R D' B' F D' F' D2 (29 moves)

Final: F' D L R' B R B R B R' B' U' R2 D' B' L D2 L' B2 R D' R' B' D' B' (25)

Tried a different start and used a sune insertion

L2 B L' R' U L U D L U // 2X2X3
(B U' B D B' D' B2 U)//3C3E

Skeleton: L2 B R' (1) L' U L U D L B2 D B D' B' U (2) B'
(1)= R D R' D R D2 R' D2
(2)=U' L2 F2 R2 D' F2 L2 B2

Final is 27
 
Won German Nationals with a 25.33 average, tying my PB from last year's nationals :)

24, 25, 27 = 25.33

Nothing fancy in the solutions.

The other two solutions are not worth sharing as they were just bad ...

Speedsolving weekly comp solution:

(L B2 F L2 R U B' U L' F D' F' D) // F2L minus 1 edge

Skeleton (17 to L5C): R' $ B R B' D' F D F' L U' * B U' R' L2 F' B2 L'

Really happy with this solution. Ties my PB! :D
Oh also, insertion finder didn't find anything for this one; can it not do 5-cycles of corners?
