I did not have any good DR. only had 10 4b5, 12 2c3. so I halfly gave up.
first time using dr flip

D2 L' B
L' D (B2 L U2 L U) // 10 4b5
U2 F2 L' D2 R // fHTR 15

dr filp:
D2 L' B L' D U2 F2 L' D2 R
(R2 D2 R' D2 R) // variate the 2e4c to get 15 gc

but still bad, so I changed abit(bracket is the changed part):
D2 L' B L' D U2 F2 <R' B2 L>
(R2 D2 <L' F2 L'>) // var, more easy to reach HTR
(U R2 U2 F2 R2 U) // extended HTR
(F2 R2 D2 U2 B2 U2) // actually I had 4 more moves to E but I couldn't find +1 so I just write with the simple way

U' F B
U2 L'
(D F2 U' L2 D' L) // 11 2c4
(D') R2 U' F2 D R2 D
R2 F2 U2 L' R U2 L' R

think I probably miss something.

missed 23:

(D) U' B2 R2 U' R2 B2 U'  // htr-drud           (8/8)
(R2 D2 R2 B2)             // fin                (4/12) 

(2c3 -> 4b2 4e path)

(L2 F2 D')
(B2 R) F' R2 B' D2 F2 R // 11 4b2 2e
U2 F2 U2 B' R2 B' 
F2 D2 F2 U2 L2

backup 23:
(F2 L2 D)
(R) B' U2 R2 B' R2 B R' // 11 2c3
L2 B R2 B' R2 B 
R2 D2 L2 F2 B2 D2 // 23 s
+0
(actually this slice is -1 for 22..)

60 eos checked, ironically my best is from 3 mover

42

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

wondering if I missed something or just scramble is bad..

(L F R' F2 U)
(R')
(F R B' R) // 10 4a2 4e
F R2 B2 D2 B' 
R2 U2 F2 R2 U2 R2 D2 // 22 s
+0

first time trying 5 EOs rush

only got
L' U L2 B' D
(F' B D2 F' R2 B L)

18 HTR 25 slice and no time

L R B' R
B2 D
(F' B' U' L2 F2 U) // 12 4b2 4e
L2 U2 B' R2 D2 F'
U2 F2 U2 L2 F2 L2

(U2 L2 D' R')
(F D) (U2 F' U2 B U) // 11 4a2 4e
U2 B2 R2 F' U2 B2 L2 B'
F2 U2 R2 F2 U D' F2 U' D'

---

optimal after DR:
D2 B2 R2 B' (R2 B2 R2 B')  // htr-drfb           (8/8)
(R2 F2 U2 L2 R2)           // fin                (5/13) 
^^;;

what I had but abandoned:

D B’ U F’ 
L’
U F2 D2 L2 U’ L // 11 4b3
-> 7+5=23

D B’ U F’ 
L’ 
D’ F2 D2 R2 D L // 11 4b3
-> 7+3=21

(D’ U2 R)
(F)
(U2 R2 U2 L2 U D2 F) // 11 2c4
-> 8+4=23.

L F' L
U2 F
(F2 R2 U' B2 U B) // 11 4a1 4e
F2 U2 R2 F2 R2 F2 D // 18-1
B2 U2 R2 B2 R2 F2 B2 // 24-1

(L) B2 U R'
D (U2 F2 D2 B' D) 10 2c3 4e
F (F2 L2 B2 L2 B' L2 B')
L R B2 L' R' U2

missed +5 HTR sad

B (U' D R F')
(R D)
(R U2 B2 R D) // 12 2c3 4e
(R' U2 L D2 L')
(D2 F2 L2 F2 L2 D2 F2 L2)

R2 B' L R
U' F (U D L2 D' B) // 11 2c4 6e
(D2 R2 U) D' R2 D' R2 D' 
F B' D2 R2 F B

hard scramble, had no good DR

R2 B L' R 
F' U B' L2 F' R2 B F2 U // 13 4b2 4e

tried this, but got nothing.

R2 B R2 F
D' R' D2 F2 U' // 9 4b2 6e wow
R (U2 B2 U2 L') // tried every varitaions of DR and HTR but couldn't find with normal 4b2 way, just tried this 4b2->4a1
(D2 L2 U2 F2 D2 F2) // 20

_______

firstly

R (U2 B2 U2 L)
(U2 R2 # F2 D2 F2) // 19 2e2e

and noticed # = R2 U2 L2 D2 L2 U2 6-5.

(U B' L' F')
(D' R') 
(D B2 D L F2 L) // 12 4a2 6e
D (B2 U') // ??
(R2 F2 D2 R2 U2 L2 B2 D2 L2) // 24

this DR has 23:

D' L2 U' D' (B2 D)  // htr-drud           (6/6)
(F2 L2 F2 L2 F2)    // fin                (5/11) 

had 11 4a1, 11 4a2, 11 2c3, 11 2c4 easy... but all bad.
for 4 move EO, mallard gives 23 for optimal.

(B' F2 U F) 
(L' D')
(L B2 L' D) // 10 4b2 4e
(L2 F2 D2 R F2 D2 L)
(U' D' B2 U' D F2) // 23 s
+2
