    Nice one - keep it up!

    With your start I can get a slightly shorter skeleton (with the same number of unsolved corners) but the insertions are actually worse.

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

    F B R2 D R' U2 @ R2 U' // XCross given [8/8]
    B' L D B L' // F2L-1 given [5/13]
    R' * B R B2 D' B D2 // AB4C [7/20]
    Insert at *: R' F' R B R' F R B' // 1 corner, from IF [4/24]
    Insert at @: D' L2 D R2 D' L2 D R2 // last 3 corners, from IF [6/30]

    Solution: F B R2 D R' U2 D' L2 D R2 D' L2 D U' B' L D B L' R2 F' R B R' F R2 B2 D' B D2 (30 moves)

    Thank you @theos for looking at this and for the different solution. I really like to see others opinions when it comes to FMC and it helps me think about different things and to also pay attention to different things next time or just in general for the future. Thank you again for your solution.

    What does the AB mean in AB4C?

    "All but" so when you see AB3C it is just a short way of saying "All But 3 Corners are solved".

    Really nice scramble I got in practice:
    R' U' F B U2 L2 B F2 R2 D2 F R2 U R B' F' D2 L2 D L F2 U R' U' F

    Lots of potential from the start and everything seemed to work out so neatly to end with a 3 corner skeleton.
    pseudo-2x2x2: L' F R2 B [4/4]
    pseudo-2x2x3: (B' L D' L) [4/8]
    2x2x3+EO: F' L [2/10]
    F2L-1: F * D2 F2 [3/13]
    AB3C: F D2 F' D F D' F' [6/19]
    Insert corners at *: F' D2 F U F' D2 F U' [6/25]

    Solution: L' F R2 B F' L D2 F U F' D2 F U' D2 F' D2 F' D F D' F' L' D L' B (25 moves)

    I agree, and I hope/think it would be nice to see the scramble, if someone is able to post it in a few day.

    I'm one of the people who got a PB on the second scramble at Tarnby, so here:
    Scramble: R' U' F R2 D B2 D L2 F2 U' L2 R2 U L' B D' U F D B2 F2 D R' U' F
    Inv Scr: F' U R D' F2 B2 D' F' U' D B' L U' R2 L2 U F2 L2 D' B2 D' R2 F' U R
    On inverse:
    L' F L B //2x2x1 4/4
    R D R D2 L D //2x2x3 6/10
    U2 R U2 R' U' //F2L-1 5/15
    F' R' F R2 U' R' U F' //A3C 8/23

    Skeleton (23): F U' R U R2 F' R F U R U2 R' U2 * D' L' D2 R' D' R' B' L' F' L
    Insert at *: L' U L D' L' U' L D - 4 moves cancelled

    Final solution (27): F U' R U R2 F' R F U R U2 R' U2 L' U L D' L' U' D2 R' D' R' B' L' F' L
    This was the fourth best solution on this scramble, after Jakob (23) and the Egdal brothers (both 26).

    I tied my official PB on the first attempt with a 39. This beat that by 12 moves. I don't really do FMC, was kinda speechless. Sadly, I DNFed the mean (only needed to sub 67 to beat official PB mean) because I'm an idiot who doesn't understand NISS properly.

    This past weekly competition (week 24), I was pretty happy with my FMC attempt. I got a 31, and got my first podium, 3rd, on anything in the weekly competitions. The only part of the solve where I was a bit disappointed was in my insertion. Checking insertion finder, it showed better results, but with weird commutators I don't quite understand. Can anyone help explain them to me?
    Scramble: R' U' F D2 L' F L' B' L' D2 B2 U L2 F U2 B2 R2 F U2 B U2 B2 R' U' F

    My insertion was only three edges, but for the sake of brevity, I'll use the one skeleton and show all three insertions solving the same case in it.

    Skeleton: B' U F' D2 B' L' D L' R D' L (1) D R' (2) D L D' B2 (3) R' (4) B U R2 F

    1 (mine):
    B' U2 D2 F D' F' U2 D2 B D
    Cancels 1
    Simple commutator, [B E2 B', D']

    2:
    R D R' B' L' F' D' F L B
    Cancels 3
    I think this is just a non-commutator 3-cycle, so I'm not mad I missed it.

    3:
    F' B U' R' U F B' R' D R
    Cancels 3
    This one I don't get. It boils down to [S, R' D' R], but i just can't make sense of it. I don't see the insert/interchange I recognize commutators by. Logically, S seems to be the interchange, and R' D' R the insert, but they "cross axes," as best as I can explain it.

    4:
    R F' B U' R' U F B' R' D
    Cancels 3
    This one is the same sort of thing, only this time it's [R: S, R' D' R], which, now that I think of it, is just the exact same thing as the last one.

    Mostly I just want an explanation of the third one, I guess.

    Any ideas for continuing from:

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

    L2 D R2 F' L2 R' B' R B2 R D' R' D R' B D B2 //F2L-1 (17 moves)

    Getting started in FMC (because of mental breakdown comp) and couldn't continue that scramble very well.

  12. x2 y2 F R U R' U' F' y2 U2 F' U F

    That leaves 3 twisted corners, and you could insert 2 comms for that for a total of 33 moves (via insertion finder).

    TBH, 17 to F2L-1 isn't great, especially since you don't have full EO, so I would try to find a better start.
