Cool! I used 7c8e DR. Optimal from DR is 22 and it is easy to find from inverse but I was super low on time when I found this DR so quite ok with this

D2 U' L' B' //EO
D' //rzp 4c4e
L' U2 L D' F2 R2 U //DR 4a2 4e in 12
R B2 U2 R2 D2 [L' //HTR in 18
F2 D2 B2 D2 B2 L2] //slice in 24
[] = L R2 B2 U2 F2 U2 F2 R2 //+1

(U2 F' L) //EO
(F' D) //rzp 3c2e 5/25
U2 B' U' F U' //DR 2c4 10/25
(L2 B) [F U2 L2 F D2 R2 B'] //HTR 19/25
L' R' U2 L' R' //slice 24/25
[ ] = B L2 D2 F R2 U2 B2 F //+1 25/25

The DR is actually 15 move optimal :/ First time seeing that on a 2c4

(D' F2 R U) //EO 4/23
(R) //rzp 4c4e 5/23
(B' U2 L) //DR 2c4 8/23
F (U2 B2 D2 B' D2 B L2 B') //HTR 17/23
(U2 F2 L2 F2 D2 L2 F2) //solved 7-1 = 23/23

F2 L2 R' F , D' //rzp 3c2e 5/24
(R' D2 L U' R' U) //DR 4a1 2e 11/24
L (D2 R B2 R2 B2 R) //HTR 18/24 standard extension from (D2 R' B2 R)
(B' F L2 B' F' D2) //finish 24/24

L' U' //rzp 4c4e (wow!)
B2 L2 F' L2 F L' //DR 4b2 4e in 8
(U2 B) D2 B^ R2 B D2 B'^ //HTR in 16
R2 B2 U2 L2 F2 R2 //slice in 22
^=w //solved +0

DR was 20 optimal but all 20 and 21 solutions were of the same form and hard to find:
L F D2 B L2 F U2 R2 U2 D2 B U2 F2 (13)
You would need 3 moves on inverse to go to 2c3 4e and then switch. Really hard at least for my level.

F' B' U B' //EO 4/22
R2 D' //rzp 4c4e 6/22
R D2 L' B2 U //DR 2c3 2e 11/22. 
(L D2 L' D2 R2 U2 R) //HTR 18/22 standard extension from (L D2 L D2 R)
(D2 B2 D2 F2 U2) //finish 5-1 = 22/22

Only 3 sub5 EOs but luckily one gave 2c3 2e in 11.
Just missed a DR like this earlier this week so good to see I'm capable of learning things :D

(L2 B' D') //EO 3/23
(L)  //rzp 4c4e 4/23
(F' R' D2 F2 R) //DR 9/23
(F' %) R2 U2 F R2 U2 F'^ //HTR 16/23
U2 R L' D2 R' L //slice 22/23
^=w 
%= S //+1 solved 23/23
HTR is 22 optimal but unfortunately I missed the double slice finish:
(F) R2 U2 B U2 L2 B L R U2 L R' D2

Also I had this 22 to slice
(L2 B' D' L) //rzp
D2 R2 F R2 U2 B L //DR 2c3 2e in 11
F' D2 B D2 L2 B //HTR in 17
U2  R L' F2 R' L' //slice in 22
But apparently it is +4 (wtf?!) moves optimal slice according to slicey finder. Never had that before. And it is not even 1qt but 3qt to work with.
