Oops! Typo. Should be R' instead of R2, I’ll edit that nowThe other two seem to work fine, but this first one seems to not work right on the CO. Typo somewhere? Or am I doing it wrong?

EO is a very nice way of beginning a solve, especially if it’s only 3 moves or so, and it also usually makes blocks easier to build. EO is actually the very first thing I check whenever I start FMC.I saw that a lot of good fmc solves almost always begin with EO. Is that just a generally good way to start the solve instead of immediately looking for blocks?
I've been doing a bunch of practice solves, and I just can't break the sub 30 barrier.
Here's my latest one, I got pretty close but couldn't find a good insertion:
Scramble: B2 R2 D2 U L2 D' F2 R2 F2 U2 L' F' R D U B2 L2 B2 F D
Solution: R2 U' L U' F2 B' L2 B2 L B L' U L U' F' L F U L' U' L2 B' U2 B U2 B2 U F U' B2 U F'
R2 U' L U' F2 //2x2x2
B' L2 B2 L B //2x2x3 + preserve pairs
(U B' U2 B) //F2l-1 + preserve pair
(L2 U L U') //square + pair on last layer
(F' L' F U L' U' L) //orient and place edge pair and square
Skeleton: R2 U' L U' F2 B' L2 B2 L B L' U L U' F' L F U L' U' L2 B' U2 B U' *
Insertion: * U' B2 U F U' B2 U F'
32 moves
Couldn't find a better insertion with more than 1 move cancel. Checked insertion finder later and it also only gave 1 move cancels. Unlucky.
I rarely ever use EO starts and I strongly prefer blockbuilding starts. 80% of the time when I do an EO start and build blocks from there, I end up having two of the "wrong" faces left to solve… (E.g. EO on the F-B axis, and I solve a block on DB, leaving U and F faces free. But F and F' moves destroy EO!)I saw that a lot of good fmc solves almost always begin with EO. Is that just a generally good way to start the solve instead of immediately looking for blocks?
An Interesting FMC Skeleton-
Scramble: R' U' F U2 L2 F R2 D2 B2 F' R2 U2 B D2 U' L2 B D' L' B' R' D2 U' R' U' F
L2 F L' // EO (3)
U' L2 B F // Five Pairs (4)
U2 B L2 F2 // Combine (4)
U2 D // Two Pairs (2)
B' U2 D2 F // Combine (4)

This is an example of what I call “freebuilding”, where you don’t have a specific blockbuilding substep or goal, such as 2x2x2 or F2L-1. I believe I shared a 23 move solution recently in this thread using this idea. I think this way of solving is “objectively superior” but I want to know what you think about it.
But also, I don’t know many 2c2e algs, only like the 10 move J-Perms, and really I’m just not great at insertions in general, so if you could show me a nice way to finish my FMC practice solve that’d be great
Solutions+thoughts for my 24.33 NR (AsR #2) mean at Medan Farewell 2019:
R' U' F L2 B2 R F2 R' D2 L2 R U2 F U R' F' L2 D2 F' R2 U L2 F2 R' U' F, 25 moves
(B) R U' B'//EO (4/4)
D L (R2 L2 B2 U2 L' U L)//DR (9/13)
(D2 L2 D' R2 D F2)//6e (6/19)
R U' B' D L F2 D' R2 D L2 D2 * L' U' L U2 B2 L2 R2 B'
*=D2 L2 D2 R2 ** U2 R2 (6-5/20)
**=R2 F2 L2 D' L2 F2 R2 U' (8-3/25)
Final: R U' B' D L F2 D' R2 D' F2 L2 D' L2 F2 R2 U R2 L' U' L U2 B2 L2 R2 B'
This is my first official solve with domino reduction, insertions were lucky though
It’s important to remember that FMC isn’t linear in the 1 hour format that we have in competitions. Wong probably tried all of the possibilities that he thought were viable. I personally go on the inverse when I find something not-so-great on the normal scramble. Please correct me if I’m wrong, but one has a lot of time to play around with things during FMC, and what you’re tackling about ties into that.I noticed that in many of people's EO often involves a NISS. When do you decide that you want to go inverse and is it really that much better?
For example in that solve, you used a switch to solve EO, however there is a 4 move EO on the normal scramble as well, and I can't immediately see why one is better than another. You do a B move on the inverse, so does that have something to do with the DR step, like with you orienting 3 corners and placing one E layer edge on the E layer? Or is it something else I am missing?
I tried the 4 move EO on normal, as well as the 3 move EO on the inverse, but I couldn't find any good continuations off thatI noticed that in many of people's EO often involves a NISS. When do you decide that you want to go inverse and is it really that much better?

I then noticed if I do a B on inverse it will leave a 3 move EO on normal so I gave that a try too.
If that did not work out I would most likely have tried EO on a different axis but luckily it worked out.
(Assuming white-top green-front; adjust accordingly otherwise.)How do you determine how many moves it takes to do EO on the inverse without actually going to the inverse?
(Assuming white-top green-front; adjust accordingly otherwise.)
If the white-green edge is bad on normal, then the UF edge is bad on inverse; if the white-blue edge is bad on normal, then the UB edge is bad on inverse; etc. It also works the other way: if the UF edge is bad on normal, then the white-green edge is bad on inverse, and so on. If you make use of this, you'll never have to actually do the inverse scramble to find where all the bad edges are.

Edit: Haven't spent much time on this scramble but 2 people got 21s on this: R' U' F L2 D R2 D B2 L2 R2 F2 D R F2 D' R2 F R' U L' D2 L' U2 R' U' F
Northern Virginia Summer 2019, scr 3.
The 21 solution:
L F2 D B F R' // 222 + pairs
L B L B2 L' // F2L - 1
L D L' D' L D L' // F2L
L' D' F' D F L // LL
definitely not something I would ever try
This makes sense. Thanks

Lol yeah, I found that in like the first 20 minutes of the attempt. I already had a 28 and a DNF(36), the DNF was because I thought I had the insertion written wrong, so fixed it, but it turns out it was right all along lol. Then on the last attempt, I was still pretty mad about the DNF (because I wanted to qualify for nats) so I was just angrily messing around with the cube and found this lol. I jumped up really quickly (kinda making a scene lol) and turned it in, Blake saw this and was like.. hey maybe I should try something different, and found this.The 21 solution:
L F2 D B F R' // 222 + pairs
L B L B2 L' // F2L - 1
L D L' D' L D L' // F2L
L' D' F' D F L // LL
definitely not something I would ever try
What's a "good" movecount to do DR in if you are aiming for sub 30?
Scramble: U' B' L2 U2 F' U B2 D' L' D2 B L2 B' R2 B R2 D2 F2 U2 R2
F' D F // EO
D' U' L'
D' U' L' U L
U' L' U L // DR (15 moves)
