Thanks everyone!

Here are my solutions:

1. Scramble:
Scramble: L2 D L2 U B2 U F2 U' F L F2 L' U2 R2 D2 B D L2 F'
Inverse: F L2 D' B' D2 R2 U2 L F2 L' F' U F2 U' B2 U' L2 D' L2

Start on Inverse:
L2 D L2 U B2 - 1x2x3 - this was a quite obvious beginning for me, the rest of the solution is just trial and error.
switch:
F L2 D' B' D2 R2 - 2x2x3
R U2 R' - F2L-1
switch:
U F' L F2 L' F' U' F - Finish + Skip

Solution:
F L2 D' B' D2 R' U2 R' F' U F L F2 L' F U' B2 U' L2 D' L2 - 21 Moves

This is actually a controversal solution due to some similarity to the inverse scramble. It is the same start + ending like the inverse scramble, but there is a different part (to be exact: the switch-part on the inverse Scramble).
I first realised this when I wrote down the solution and thought it was the full inverse solution. (Later Sébastien told me that it's not the exact inverse scramble). Luckily I did not find the skip on the normal scramble, it would have been a 19 and the full inverse scramble.

After I stopped this attempt and gave my solution to Geert I discussed with Sébastien, I think we should consider some other scrambles for FMC in the future. The best idea I have is to just have scrambles with a lenght of 25 moves, so the inverse scramble is maybe a considerable solution, but not a potential sub20 solution (and right now: also Single WR).

EDIT: Also there occured some case in the US some time ago, that there was a solution with 18 moves which happen to be the inverse scramble. Luckily nobody found this solution, but there happened to be a discussion here in some thread.

2. Scramble:
Scramble: D2 L2 F' U2 F L2 F L2 R' U R' U2 L' F R' B U' F2 R' D'
Inverse: D R F2 U B' R F' L U2 R U' R L2 F' L2 F' U2 F L2 D2

Start on Normal:
B U2 L U - Pseudo2x2x2
switch:
U R' U - 2x2x2 + 1x2x2
switch:
F D R D' R - PseudoF2L-1
switch:
F2 - F2L-1
switch:
D F D' F' D2 F D2 F' - Finish

L3C:
B U2 L U F D R D' R D . F D' F' D2 F D2 F U' R U'
. = R' F L F' R F L' F'

Solution:
B U2 L U F D R D' R D R' F L F' R F L' D' F' D2 F D2 F U' R U' - 26 Moves

3. Scramble:
Scramble: D2 R2 U2 R2 F2 U2 F U2 F2 R' B2 R' D2 B F2 D' L D2 F U'
Inverse: U F' D2 L' D F2 B' D2 R B2 R F2 U2 F' U2 F2 R2 U2 R2 D2

U2 B2 - Some Premoves
switch:
D' L D' - 1x2x2
R' F2 R F R F' - 2x2x2
B - 2x2x3
sw:
L' U2 L U2 - PseudoF2L-1
L' U' L F' L F U L U - Finish + Skip

Solution:
U2 B2 L' U2 L U2 L' U' L F' L F U L U B' F R' F' R' F2 R D L' D - 25 Moves

I have to admit - I was kind of lucky to have two solutions with a skip. Also it was kind of unexpected, but right now I am happy about my results.

I am looking forward to see this mean being broken in the future. There are a lot of people who have the potential to break this WR, I am curious what will happen in the future :)

Congrats Linus :D
Using your F2L - 1 on the second scramble I found a 25:

B U2 L U // Pseudo2x2x2
(U R' U) // 2x2x2 + 1x2x2
F D R D' R // PseudoF2L-1
(F2 D2) // to 3c3e

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

B U2 L U F D R D' R # D' F D2 F' D F2 U' R U'
# = [B, D' F D]

B U2 L U F D R D' R B D' F % D B' D F' D F2 U' R U'
% = [F', D' B' D]

Final solution: B U2 L U F D R D' R B D2 B' D F D' B D2 B' D F' D F2 U' R U' (25)

interested in seeing Sébastien's solutions

Thanks again everybody! :)

I agree to some of the arguments that this are kind of weird rules to get platinum member. But on the other side I can understand that you just can have it when your history of world/continental records is finished. Maybe there could be two different versions of platinum member :)

At least besides me there is only one person affected by this (Simon Westlund). All other gold members are missing more than just CR (e.g have WR but no Worlds podium/missing WR, CR, ...)
