Scramble: R' U' F R' B' U2 D F2 R' L2 F U' B2 D2 R D2 R D2 F2 R' B U2 R' U' F
Solution: L D F U F' D' F2 L F2 L2 F2 L U L U B2 F U B2 U' F' U B2 (23)

L [1] F U F //EO (4/4)
L F2 L2 F2 //222 (4/8)
L U L U //2 squares (4/12)
B2 [2] U //2c2c (2/14)

[1] = D F U F' D' F U' F' (8-5/17)
[2] = F U B2 U' F' U B2 U' (8-2/23)

This was a nice scramble. I also found:

(R F R F) (R F2 B2 L' U) //DR in 9
(R' F R' F) (L U2 R' D) //DR in 8
(U' B U' B) L U2 L2 F2 R U' R' U' L F2 U R U' R' //3c in 18, gives 24

And other DRs in 10 or more

B D //EO (2/2)
F (L2 D2 F' R F) //DR with magic D2 (6/8)
® U2 L' //HTR (3/11)
D2 * U2 F2 U2 D2 L2 //3e (6/17)

* = F' B' L2 F B' U2 (6-3/20)

Another super easy scramble. Apparently optimal DR finish

F' U' R L' B //EO (5/5)
R' U2 F2 [c] R' D' //DR (5/10)
R [e] B2 U2 L' //3 pairs (4/14)

[e] = R2 F2 D2 B2 L2 F2 U2 B2 (8-5/17)
[c] = U2 R D' R' U2 R D R' (8-1/24)

Optimal finish was maybe findable:
B2 L U2 B2 R' F2 R F2 R B2 L2 (11)

23, 20, 24 = 22.3 :O
