My scaling is the same as Murdr's, and I don't think we ever discussed it.
I think it's interesting that there are a lot of people who think that there is a
secret to scaling that gives someone an edge.
I have seen people fly well with all kinds of scaling, including all sliders all the way to the top on all axes. All sticks and people are different, and we all adapt and modify to our own level of hamfistedness.
If there is a secret, it might be running aileron sliders all the way to the top. I have never understood why someone would not want a 1:1 ratio of stick throw to control surface for roll. You aren't pulling any g's with roll, you set your bank first in so many instances and many maneuvers (offensive and defensive) are better performed with as fast an initial roll rate as possible.
The perceived "agility" of an aircraft is directly related to roll rate. If you don't have aileron scaling all the way to the top, I strongly encourage everyone to try it and feel the difference. You can always set it back if it doesn't suit you.
