I hate 5-moves EO

(R2 B' D' B R') 
R2 D' F' U F' D // 12, l3e, but I'm not good at 3e insertion, so just solve it.... what make me lose chances to get 17, what is opt of this scramble......
R' D' L D R L' F' L' F L 

It's may not straight, because it's something improved from

L // 122
[R2 F' U] // p223
(R2 B' D' B R') // f2l-1
F D' F2 D // 3c3e

After  f2l-1, I noticed that p223  [R2 F' U] can be rewrite 
as [R2 D' F' U F' D], and will get a 3e remained.
(in fact, it's a 3c inserted with 8-9 lol)

and if say there is a 17 with insertion:
L
(R2 B' D' B R') 
R2 D' F' U F' @ D  // 12 3e
@: F' D R U L F L' U' R' D' // 10 - 5....

R U B L F L // 222 and some pairs, with inserted R at first position
(R B R' D' R' D R') // 13, 3e4c, 4c is 3+1

first to insert sexy move to solve edge.
skeleton: R U B L F L R D' R D R # B' R'
#: D' B, L B' L' B, B' D // + 8 - 2 l3c, pretty lucky to get this.

skeleton2:

What a BB week....
I only found a few 5-moves...so just BB.
