First week, scramble 1:
Scramble: R' U' F U' B D2 U2 L2 F R2 F' U2 R2 U2 R2 B' D' F D R' D R2 D R' U' F
Solution: L2 U' R' U2 B2 L2 U' B2 U2 F2 U L2 F2 U' L2 D U2 R' L' F2 B L2 (22)

Spoiler (Click to View)

(L2 B') //EO (2/2)
(F2 L R) L2 U' R //DR (6/8)
(U F2 [2] D B2 R2 U' F2 [1] U) //HTR (8/16)
(L2 B2 U2) //2e2e (3/19)
[1] = F2 U2 B2 [4] D2 B2 U2 //Slice (6-4/21)
[2] = F2 D' U L2 [3] D U' //Solved (6-4/23)
[3] = [4] = E2 (-1/22)

Unfortunately, I could not find a way to slice to 21.

I got a 22 (and some 23s) also from the DR in 7 (without the F2):

(L2 B') (L R) L2 U' R
(D2 B2 F2 D R2 D2 U' L2) 3c in 15
Multiple ways to insert for +7

After the L2 U' R on normal one can add any combination of HTR moves and get many variations of this DR, I should have tried more. But in the the only sub-20 from (L2)L2U' was from my 8-moves DR (found with nissy):

(L2 B')
(F2 L R) L2 U' R
D F2 D' B2 L2 D' B2 D2 B2 R2 D
