(U2 L2 U2 R2 F2 D2 L2) //Finish (7/21)

I worked on this DR for ~30 minutes, I found also two 21s from HTRs on normal:

L2 D2 F2 D2 R'
D2 R2 U2 L2 B2 R2

R2 U2 B2 U2 R'
U2 R2 D2 R2 B2 R2

I am noticing only now that they are the same solution, sliced.

Unfortunately I missed the optimal finish, though I was close:

L2 D2 F2 D2 L' F2 U2 R' L' D2 (10)

23, 23, 21 = 22.33
