Week 3

1.
Scramble: R' U' F D F' R' B2 R2 D' R2 B2 D U2 R2 F L R' B2 D' R' F U2 R' U' F
Solution: D2 L' R F2 L R' U2 F L2 D2 U2 L B' F2 R2 B' F' L2 R2 F R F D' U R' (25)

(R U' D) // EO (3/3)
(F' R' F' R2 L2 F B R2 F2 B L') //DR (11/14)
(U2 D2 L2 F' U2) //HTR (5/19)
(R L' F2 R' L D2) //Finish (6/25)

I found it like this:
(R U' D)
(F' R' F' R2 L2 F' B' * L2 B' L') //DR in 13, 1q
(R2 B') //HTR -1e
* = F2 B2 R2 F2 B2 L2 //HTR in 16

But then I could not find a good finish.
So I switched after the 14 move DR, and the finish was easier to find.

L D F R2 U //EO (5/5)
F2 R' B R2 F L' D2 L' //DR (8/13)
B' U2 L2 B' //HTR (4/17)
R2 L2 U2 B2 U2 F2 L2 U2 //Finish (8/25)

I also had a few HTRs and a couple of 25s from this DR:

(B' D R)
(U' F L2 D R2 D B2 D' F)

Scramble: R' U' F L B2 D2 B L2 B L2 B2 L2 F' U2 F' D' L B' D2 L D F D2 R' U' F
Solution: D2 F2 U2 B' U2 B' D2 R2 D2 B2 D2 R F2 R2 B2 L2 B D2 L2 R' D' F' R2 F2 (24)

(F2 R2 F D) //EO (4/4)
(R L2 D2 B [2e2e] R') //DR (5/9)
D2 F2 U2 B' U2 B //HTR (6/15)
D2 [3e] //2e2e3e (1/16)
[3e] = D2 B2 D2 R2 D2 B2 D2 R2 (8-4/20)
[2e2e] = B2 L2 B2 R2 F2 R2 (6-2/24)

Optimal from this DR is 21, but none of the 21s or the 22s has less than 4qt.

25, 25, 24 = 24.67
