did not find anything decent...

I think this is the shortest
dr I have found until now.

F' L U R                    // eo (4/4)

`F' L U R U2 F' U F' L2 B2 L2 B2 R2 U2 R2 F R2 F L2 U2 B' (21)`

U2 F' L2 B      // eo (4/4) dr-7c8e

U2 B2 U2 R F2 L // htr (6/16)

`U2 F' L2 B U D R D' R2 D U2 B2 U2 R F2 R' D2 R L D2 B2 D2 (22)`

Also found this 23 pretty early:

(R U' R L D)        // eo (5/5)
(F R U2 F2 R2 B L)  // dr (7/12)
(U2 B' R2 U2 B)     // htr (5/17)
(L2 F2 L2 U2)       // ls (4/21)

+2 to finish

(D2 B U2 R)                 // eo (4/4)
(U F' R2 B2 D L2 D')        // dr (7/11) 3q2c
(B2 R2 F' D2 B L2 U2 B')    // htr (8/19)
(U2 B2 R2 F2 R2)            // fin (5/24)

I missed this dr->fin though:

(B2 R2 F' D2 F U2 R2 F)
(L2 B2 D2 R2)

Miswrote my solution...

B' L' U' D' F               // eo (5/5)
U2 F2 L2 U2 R'              // dr (5/10)

L2 F2 U2^ B2                // ls (4/23)

^widening                   // fin (+0)

happy that I found this.
briefly tried a few of the dr variants,
but did not find anything.

D' F B2 R' U            // eo (5/5)
F' L2 B' L' B2 L'       // dr (6/11)
(U2 L2 F R2 D2 U2 F @)  // htr (7/18)
(U2 R2 F2 @ D2 L2)      // ls (5-1/22)

@ S2                    // fin (+1)

Quick and easy 23. I'll take it.

L D' (B' U)                     // eo (4/4)
(L' D2 B D2 F R)                // dr (6/10)
(B L2 F') B2 R2 F' R2 B L2 B'   // htr (10/20)
D2 @                            // ls + some edges (1/21)

@ D2 L2 B2 D2 L2 B2 L2 B2 D2 F2 // fin (10-3/28)

I did not find any other drs than this one :(
Was running out of time
and had to just solve the
cube to get a mean.

There were these 22s from my dr:

F' U2 F' R2 D2 B2 D2 F' L2 F' D2 B R2 (13)
B' R2 B' L2 U2 B2 U2 F' R2 B' R2 F R2 (13)
B' R2 B' L2 U2 B2 U2 B' D2 B' D2 B R2 (13)

I tried D2 B U2 F (R2 ...),
because I originally wrote the eo as
L D (B' U). Maybe I should force myself
to check if adding a double move is +0
at the beginning of dr, and marking it
as a possibility.

L' F' L F'           // eo (4/4)
R B2 D2 R2 D' R     // dr (6/10) 3q2c4e
(F2 U) B2 R2 D F2 D // htr (7/17)
F2 L2 D2 B2 D2      // ls (5/22)

I then wrote the dr->ls on normal and cancelled a move:

B2 R2 D F2 D^ F2 L2 [D2 B2 D2 U' F2]
[] => U2 F2 U^ F2   // ls (-1//21)

finally:

^widening           // fin (+0)


---


I initially thought it was 22 (my dr initially ended with R'),
so I was happy when I realized it was 21 :)

After finding this at 40 minutes
I went on to check other drs:

(U' D R)            // eo (3/3)
(B' L2 U L2 B')     // dr (5/8) 4q4c

(U' F L D')         // eo (4/4)
(L D2 U2 R' U2 R')  // dr (6/10) 3q2c

(R' B' R2 B)            // eo (4/4)
(L' R2 U D' R)          // dr (5/9) 3q4c
[U R2 F2 D2 F2 D F2 D'] // htr (8/17)
B2 R L D2 R' L'         // ls (6-1/22)

[] => D B2 R2 D2 R2 D' U2 L2 U' // fin (+1)

I found the slice by first inserting to +2, but then noticing that I could insert E2 E2 to cancel a move. not optimal.

.

tried to finish this dr.

F R L B
U' L' D2 L' B2 R2 L U'

Pretty happy with the attempt.
Misstraced some niss eos that made me waste time.
I thought that there should be a shorter finish from the dr,
what I found seems to be optimal.

R' D' (U2 B' U)         // eo (5/5)
(F' R' D2 R U2 L F)     // dr (7/12) 2q4c6e
L' U2 R                 // htr (3/15)
F2 U2 R2 D2 L2 U2 B2 L2 // fin (8/13)

I only checked this dr

```
B' (D2 B)               // eo (3/3)
(U R D U2 R' F2 D2 R')  // dr (8/11) 3q4c
R2 D (F2 D B2 R2 L2 U)  // htr (8/19)
(R2 F2 U2 F2 D2)        // fin (5-1/23)
```

`B' R2 D' F2 U2 F2 R2 U' L2 R2 B2 D' F2 R D2 F2 R U2 D' R' U' B' D2 (23)`

Found 26 by inserting this 3e, but I ran out of time before writing down the solution...

```
U' B (U D' F)               // eo (5/5)
(U D' L') D U2 L U' L       // dr (8/13) switched after 8 lol
(U' R2 D2 F2 @ L2 U' R2 U') // htr (8/21)
