(F R' F2 U) //EO (4/4)
(R D2 F B2 D2 L B' L') //DR (8/12)
(F U2 L2 F D2 F) //HTR (6/18)
(* L2 F2 L2 F2 D2) //2e2e (5/23)

* = F2 D2 F2 D2 F2 D2 (6-1/28)

The scramble did not look so bad, but I could not find any good DR from the many EOs I had

I forgot to check the similar DR (D F' B L2 F' D), but luckily optimal was 20 also from there.

D2 L2 D2 B2 D2 R2 B2 R2 //Finish (8/23)

I had lots of EOs in 3 and 4 moves, but none of them gave anything good! I was desperate and I started working on the 5-move variants of these 3-movers, and finally at ~48 minutes in I found this easy DR. Optimal finish

28, 20, 23 = 23.67
