Interesting... Requires a lot of focus on insertions.
What do you think about this method?

It seems okay, but it is sightly worse than doing edges first and then doing 4 or even just 3 corner comms as insertions.

Edges first makes it so you don't need to memorize any special algs, beacuse you can always find optimal 8c or 7c with only corner commutators, so it is much simpler, so it is easier to get closer to optimal insertions than corners first.
And also just a random thing, you can use just slices to solve edges too.

Also, please note when you used Insertion Finder, because I am certain without a doubt that you did there. It's okay just for a simple demonstration, but please do not do this in a real attempt :) (I have also seen you use it a couple times in the 3x3 example solve thread, but I know there's not really anything wrong with that so don't worry :))

Perhaps I will give this a shot and see how I'll do, although probably not well :/ I like edges-first more :D

Although, I know this can be a good way of solving because there have been very, very good FMCer's that have done this frequently, but I do not recall their names I'm sorry, but I know some have gotten great results with corners first. I'm just lazy lmao.

My try at corners first:

Scramble: R' U' F D' F2 L2 U' B2 L2 B2 D2 B2 U' L' B R' B F' L' B2 D' B2 R U R' U' F (fewest-moves.info contest 190)
Solution: U D F2 B2 U' R D2 L' U B D' F B' L B' L2 F L2 R' D F' D' L (23 HTM)

U L U // corner layer (3/3)
U R' U' L U R U' L' // CLL (8-1/10)
B // solve corners (1/11)
z' y' // solve corners relative to scrambling orientation, leave 5e5e6x (0/11)

U L U2 R' U' L U [1] R U' L' B z' y'
[1] = U D' y' // 8e2x4x (2-1/12)

U L U2 R' [2] U' L U2 D' y' R U' L' B z' y'
[2] = U' D y // 5e1e6x (2-1/13)

U L U2 R' U2 D y L U2 D' y' R [3] U' L' B z' y'
[3] = R' L x // 6e4x (2-2/13)

U [4] L U2 R' U2 D y L U2 D' y' L x U' L' B z' y'
[4] = D F2 B2 z2 D' // 4e4x (4/17)

U D F2 B2 z2 D' L U2 R' D [5] U2 y L U2 D' y' L x U' L' B z' y'
[5] = B U' F B' z' U B' // Solved, was not expecting to get this lucky (6/23)

Amazing job Cale! Such a big jump in the mean record, I can hardly believe this! Nice personal best single too!

22.67 OcR mean solutions. #4WR

25, 20, 23 = 22.67

1: R' U' F D2 F2 D2 U2 R D2 L' R2 F2 R2 B2 F' L2 D' R F U' R' D L F' R' U' F

25

(U' B) L' D F' // EO
L // 2 squares
U D2 (D') // 223
D' L D L F2 U L' U' // 16 to 2c2c

L' D F' L U D L ^ D L F2 U L' U' D B' U

^ - L U2 R' D2 B2 R U2 L' D2 F2 (25)

Comment: Optimal feasible insertions, IF gives 24 but it does an 8-6 at the end to create a different 2c2c but it's in 18, giving 11-5 on a H Perm. I also had a 10 move DR on this scramble that is +13 optimal but it doesn't seem feasible whatsoever.

Solution: L' D F' L U D L2 U2 R' D2 B2 R U2 L' D2 F2 D L F2 U L' U' D B' U (25)

2: R' U' F L2 R B2 L D2 F2 U2 L2 R' D' F2 R U L' F R' B' L U' F2 R' U' F

20

U2 D' F' D // EO w/ inserted U2
B U2 B L // DR (8)
D2 F' B' L2 ^ B L2 B L2 // 16 to 3e3e

^ - U2 D2 F' U2 D2 B (21)

U2 D' F' D B U2 B L D2 F' B' ^ L2 U2 D2 F' U2 D2 B2 L2 B # L2

^ - F' B z
# - B' Bw (20)

Comment: Optimal after DR is + 11 if you make the L an L'. It seems somewhat feasible using HTR, despite the DR already being DR-2e4c (as optimal adds two moves to create HTR-4e4c then switches).

Solution: U2 D' F' D B U2 B L D2 F2 z L2 U2 D2 F' U2 D2 B2 L2 Bw L2 (20)

3: R' U' F L' R' B2 R2 F2 D2 B2 L' U2 R2 U' L' B F2 R2 U' L2 B L' F2 R' U' F

23

R (B2 D' F R) // EO
(B D2 B2 R2 B U') // DR (11)
(L2 D2) // lol what
(F' L2 D2 B2 R2 B' R2 B R2 B') // Finish (23)

Solution: R B R2 B' R2 B R2 B2 D2 L2 F D2 L2 U B' R2 B2 D2 B' R' F' D B2 (23)

Comment: I found this about 20 minutes in. There's +5 moves to HTR if you switch after DR but I didn't see it because I outright forgot about checking HTR-6e4c.

Congratz Cale!
Good to see you can mix old techniques (NISS) and new techniques (DR) perfectly

Superflip with an empty skeleton and two insertions:

Skeleton: @ #
@ = D L R F B U D L R F B U // flip eight edges (12/12)
# = M2 [M2 F2 M' F2, U'] M2 // flip the other four edges (14/26)

Final solution (26): D L R F B U D L R F B U F2 L R' D2 F' D2 L' R F2 L2 R2 D L2 R2

Spent some nonzero amount of time trying (and failing) slicey shenanigans for the 4-flip.
