Solutions for my 22.00 WR mean (16, 26, 24) at FMC 2019:
1.
Scramble: R' U' F D2 L2 F R2 U2 R2 B D2 L B2 D' B2 L' R' B D2 B U2 L U2 R' U' F
Solution: D2 F' D2 U2 F' L2 D R2 D B2 F L2 R' F' D U' (16 - optimal!)
2.
Scramble: R' U' F D2 L2 B F L2 B D2 F L D R2 U2 B L R2 U' R2 U B U2 R' U' F
Solution: U2 R' L B' R2 B L2 B' R2 B U L2 R' D2 R' D' L' D2 L D B2 F2 R' F' L' R (26)
3.
Scramble: R' U' F U2 R2 D B2 D' R2 B2 L2 F' D R2 B D' R D2 F U2 B' U' R' U' F
Solution: F2 R' D R D2 L2 F2 B2 L F L' B2 L F L' U' R2 B2 L' B' R U R L (24)
A few thoughts.
* I am obviously very happy. I have put a lot of effort in FMC lately (practicing almost every day after hours of math research/classes/teaching is really tiring!). it's nice to see hard work paying of.
* I totally was not expecting this. I thought that it was possible we could never see an official 16, and the mo3 is very low too.
* I am sorry for Mark, he only got to keep his records for a couple of weeks...
EDIT: I explain my solves in this video.
1.
Scramble: R' U' F D2 L2 F R2 U2 R2 B D2 L B2 D' B2 L' R' B D2 B U2 L U2 R' U' F
Solution: D2 F' D2 U2 F' L2 D R2 D B2 F L2 R' F' D U' (16 - optimal!)
I have found a couple of interesting EOs on normal scramble, which looked like they could lead to some nice domino solves. But I decided to switch immediately to check the inverse as well. DR + easy corners = insert right away!
(U D' F R) //EO (4/4)
(L2 F' B2 U' B2 U' * ) //DR (6/10)
(R2 B + F D2) //5e (4/14)
* = U D' F2 D U' # R2 //2e2e (6-2/16)
+ = E2 //Leaves 4x (x = "centers") (2/18)
# = E M2 E' M2 (2)
First solution: D2 F' D2 U2 F' L2 R2 {U' D B2 D B2 U} B2 F L2 R' F' D U' (20)
Replace {U' D B2 D B2 U} with R2 D R2 D, which also cancels 2 with the previous move (-6+4-2)
I don't what to say about this... a really advanced solve with lot of luck involved. I was shaking so much after finding the 16 that I had troubles writing down the first move.

Scramble: R' U' F D2 L2 B F L2 B D2 F L D R2 U2 B L R2 U' R2 U B U2 R' U' F
Solution: U2 R' L B' R2 B L2 B' R2 B U L2 R' D2 R' D' L' D2 L D B2 F2 R' F' L' R (26)
(R' L F) //EO (3/3)
(R F2) U2 //2 squares (3/6)
R' L' * U R2 L2 //223 + pairs (5/11)
R D2 R' //Pseudo F2L-1 (3-1/13)
D' L' D2 L D B2 //3C (6/19)
* = L2 B' R2 B L2 B' R2 B (7)
Kinda unlucky insertion, but this evens out with the kinda lucky insertion on the last solve

Scramble: R' U' F U2 R2 D B2 D' R2 B2 L2 F' D R2 B D' R D2 F U2 B' U' R' U' F
Solution: F2 R' D R D2 L2 F2 B2 L F L' B2 L F L' U' R2 B2 L' B' R U R L (24)
(L' R' U' R' B) //EO (5/5)
(L B2) F2 //2 squares (3/8)
(R2 U) //222 (2/10)
(L F2 L' F2 L2) //F2L-1 (5/15)
(D2 R' D' R) //3C (4/19)
Skeleton (on normal): F2 R' D R D2 L2 F2 * L F2 L' U' R2 B2 L' B' R U R L
* = B2 L F L' B2 L F' L' (5)
I have found this quite quickly, but it looks like there should be something better.. I had another 24 as well with a very similar skeleton (same 3 corners left):
(L' R' U' R' B) //EO (5/5)
(L B2) F2 //2 squares (3/8)
(R2 U) //222 (2/10)
(L F2 R F2 R2 D2 L D' R)
(L B2) F2 //2 squares (3/8)
(R2 U) //222 (2/10)
(L F2 L' F2 L2) //F2L-1 (5/15)
(D2 R' D' R) //3C (4/19)
Skeleton (on normal): F2 R' D R D2 L2 F2 * L F2 L' U' R2 B2 L' B' R U R L
* = B2 L F L' B2 L F' L' (5)
