Asking pros about mouse settings does no good because they themselves do not understand how things work. They just play better and by pure skill difference dominate. Their mouse settings (whatever they picked) stored in their muscle memory. They picked something once accidentally and use it all the time, even if it's not optimal it gets compensated by muscle memory. Many people do that too from my observations and it works for them and it is totally fine, no need to readjust.

BUT Speaking of optimal it could be calculated:

First let's cut the all the bullshit.
6/11 is the only setting you must use if you want a "pure" sensor performance. Having more would lead to software acceleration and pixel skipping, having less would lead to software slow down and not every movement reflects on the screen. Enhanced precision leads to inconsistency (same movement length, different pixel distance). You can google for this from trusted sources of your choice. The only setting you should use is DPI adjustment of your mice. 50% in game is 1:1 scaling usually (i.e. no scaling) which means 6/11 in windows. By having this set up you have 1:1 no scaling and this is a constant value in all your games no matter which mouse and monitor you use.

Then let's have a baseline and dig deeper into the history.
When BroodWar came out and became esports it was played in 480p vertical resolution (640x480) with mice that were available at the time. Any ball mouse has roughly 400 DPI, first optical mice also had 400 DPI to correspond with the ball mice to make this transition easier. Examples are most famous Logitech Mini Optical, Logitech MX300, Microsoft Wheel Mouse optical.

So we can take it as our baseline. 480p @ 400 DPI.

What if I have a modern game and new monitor that has 1080p vertical resolution? The right question is how do I adjust my mouse DPI to compensate for bigger monitor resolution from 400 DPI to something faster. You can calculate the answer:

What is the screen resolution increase factor? 1080/480 = 2.25
What is DPI increase factor? Right 2.25. Meaning you need 400 * 2.25 = 900 DPI. Good job TT1, you got the DPI right.

What if I play like Artosis in 1280x960 box on my 1080p monitor? You have effective vertical resolution in-game = 960. Same formula 960/480 = 2. 400 DPI * 2 = 800 DPI. Optimal DPI to play if you were Artosis is 800 DPI.

For 1440p monitor you have 1440/480 = 3, 400 * 3 = 1200 DPI.

What about Use Mouse Scaling setting in SC:R?
You have to first understand how it works under the hood. This setting was made to scale whatever monitor you have e.g. 1080p to feel like it's having 1:1(50%) no scaling in 480p.
It does it by adjusting your windows mouse settings (that 6/11 thing) while in-game. So IT IS SOFTWARE SCALING, and therefore it's bad, you should avoid it if you can. With Use Mouse Scaling it should always be set at 50%.
This setting is useful if you have old Logitech MiniOp Mouse/MX300 incapable of DPI change (400 DPI only). You can NOT just set it to 900 DPI to adjust for 1080p screen. What you can do instead is adjust you windows setting to 75% (8/11 instead of 6/11), and Use Mouse Scaling does JUST THAT for you.
E.g. For 400 DPI mice it would be 8/11 windows setting, for 1440p it would be 90% 10/11 with same Use Mouse Scaling and 50% in-game.
It is not optimal adjustment, but it does make things easier sometimes if you don't care how to adjust your mice via DPI or windows settings manually. The huge downside of this is pixel skipping as I described above. With Use Mouse Scaling there's always artificial acceleration factor applied to your mouse sensor (unless you play like Rain in literally 480p window in the center of the screen so it looks like a mobile game).

Since nobody tried to explain this stuff yet I thought this was necessary.

TLDR: Use whatever feels comfortable, if you absolutely want to optimize then study the topic and take it seriously, but remember it won't improve your skill and do not influence your play significantly (as many pros shown us).
