Can I have help with some efficient tricks?

Next Scramble: F R B2 L2 F2 R2 U2 F2 U' R2 D L2 U L2 R' F' D2 B R' B2 F2
I am terrible and my personal best is 52sec, at least recorded anyway, so take what I have to say with a grain of salt. At least Roux is all I ever use, so there is that.

Your F2B seems to need the most work from my perspective.

I count 33 quarter turns in the first one and 29 in the second one. I would try to work on this phase some more. If I were you, I would try to get the F2B phase to where you are averaging closer to 20.

I don't know if you have godly knowledge of placing and aligning corners, but you did do it both times here in one alg, so I can't really say you need to learn some more of those. That's probably the next best thing to do if you aren't already godly at it, though. Doing 15 or so quarters here each time rather than 15 + 13/17 is a pretty big move/time saver.

LSE looks OK. I wouldn't spend too much time trying to optimize this part. I shaved a few moves by doing this in the first one

U M U M U2 M2 U M U2 M'

That's 13 quarters rather than 17, again there's really just not much reason to try to shave here from my perspective.

The biggest gains are in shaving the fat in F2B and the corners move wise and lookahead so you can waste less time inspecting mid solve.

Oh and one other thing I forgot. If you aren't able to work with the same 2 colors top/bottom, same 2 colors front/back, and same 2 colors side/side in any order then I would try to get that way. I also can't easily see this from the solves there. You can shave a lot of moves by being able to orient however you want with top being either of white/yellow and having either of orange/red on the right side or whatever.

- Edit -
Your solve you posted there while I was writing this doesn't complete for me, but I don't recognize it as signature Roux with use of f' and u'.

If you know how to use these kinds of things from other systems, then go ahead I guess, but I think part of the benefit of Roux is that you can continually eliminate moving whole parts of the cube.

Like once the FB is done (say you are right handed) you can just lock those 6 blocks in your left hand and stick with F, U, M, R, and r moves to finish the whole thing. As you go along you also get to rule out F, R, r, and U moves (but keep U2). If you try to keep all those in play right to the end, it may reduce move counts but it probably won't reduce speed.
- End Edit -

- Edit 2 -
The backticks (button to the left of 1 on my keyboard) are killing me. I have to change them to single quotes (right of ; on my keyboard) before I an view your solves at https://alg.cubing.net

The ones in the scrambles are right.

Doing X, Y, or Z during the middle of a solve will probably cost you at least a few seconds to regrip in timed.

Anything you can do in FMC with it you can do better without it in FMC.

After some serious R&D I found this continuation for LSE that shaves a few moves

U' M U2 M U2 M U M U' M U2 M U' M U2 M'
(56h, 67q, 47s, 47e)

Because I like to feel bad, I asked Kociemba what he would do here and he found this alternative solution:

R L' F2 D2 B' R' L F2 U R2 L2 U2 D F2 D B2
(48h, 63q, 47s, 47e)

Never going to do that again.

My takeaways from that are to never ask Kociemba what he would do, ever, and when in a similar position put the side with both side colors on it to the front and then go down with it (U' M) then continue on as normal.

I am hoping that I remember this and that it somehow helps my completion speed.

(55h, 68q, 44s, 45e)

It was at this

M' U M U2 M
U' // <------
M U M2 U' M U2 M' U M2

point that I realized that I did 4c before 4b for the first time ever.

Maybe all that time I spent trying to always do LSE in 20 quarter turns or less actually meant something? Maybe it was reading this?

I don't think I can reproduce this in speed solves. Oh well.

Is any part of that last line something that you would do in a speed solve?

I would have done instead: U' M2 U M' U2 M' U' M' U2 M2 U2 M

You used a CMLL which I wouldn't expect people to know until long after the shortcut which I used which typically would lower move counts/speed but in this case it raises it.

That makes me think this solve is FMC.
