(F U' L B) //EO (4/4)
(R' F2 D' F2 R2 U' R') //DR (7/11)
(B2 D2 F2 D') //HTR, with useless B2 inserted (4/15)
(B2 R' L' F2 R2 F2 B2 L' R) //Finish (9/24)

I was very close to the optimal finish after DR, but I did not try the other useless move before HTR:

(F2 D2 F2 D')
(R2 U2 F2 R2 F2 L2)

D' R D' R2 L B L //F2L-1 (7/17)
R' U' R //3c (3/20)

* = L U2 L' D' L U2 L' D (8-4/24)

I tied the optimal finish from the first 10 moves, which was:
R L2 D' R U' R F B U2 F' B U' L2 B2 (14)

24, 21, 24 = 23.00
