Pretty bad scramble that just has this one good DR on it somehow

with <2 minutes left I realised you could do this:

B (R2 U2 B)
U (R2 * D' L' D)
L D2 L' D2 F2 L' B2 L'//2e+M in 17

*=(R2 D2 L2 U2 L2 D2)//20 to M

By the time I wrote it down properly I had <1 minute left and I didn't think it would be possible to solve it and write everything down legibly so I just didnt try.

I just tried it at home and found out it's +0... However this did make me more aware about out of DR stuff as we will soon see...

other:

U (R' U' R U)
(B2 L' F L B)//4c3 (10)

Attempt 2

Scramble

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

Results

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

R' D' B' U'
L' D2 F2 L2 * F L R//2c3 4e in 11 with cool RZP into 8e8c :) 

First I did this:

(B2 R2 F U2 B D2 R2)//almost HTR but wtf its just a 2e2e so let's backtrack:

(B2 R2 F U2 B')//almost the same
(L2 F2 U2 L2 F')//21 to S

Unfortunately this does not +0, but I remember the 2e2e incident in A1 so:

([B2 R2 F U2 B D2 R2 F' B2])//2e+S in '19'

*=L2 F2 D2 F2 L2 U2 B2 U2//8-6 insertion to leave S slice in '21'

[]->(F2 L2 B R2 F U2 L2 F)//21 final

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

Proud of this one because the scramble is bad again, it's optimal after EO too :)

I did have a backup 22 relatively quickly:

(L' R) B2 F' R'
(F' L2 U F D')//4c3 with rare 5 mover AR-4c1e 7c8e case
(B R2 F2 U2 B L2 R2 D2 F)
(L2 U2)//21 to S, +1

Attempt 3

Scramble

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

Results

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

(D) L2 D
(B') L B2 R' D2 F'//4b2 2e (9)
U2 R2 D2 F2 [L' D2 L']
B2 D2 F2 D2//M slice (20)

[]->R' B2 R L2 (21)

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

You'd think a scramble with 4 3 move EOs would be good but this is (reasonable) mallard optimal...

I only found this DR at 50 mins because I initially didn't switch this RZP due to it only having 1 pair, luckily the finish is straightforward.

other:

L F' D R'
F2 R2 U' F2 D//2c4 (9)
F' (B D2 F' R2 U2 D2 B')
(L2 D2 R2 F2 R2)//22 to slice backup, this DR is 21 optimal though

D L R F
L2 B2 D F2 D R//4c3 (10)

(L2 B2 L' D)
(F R' B U2 B' L)//2c3 6e (10)
