Ok, so the depth of the scattering is then determined by the division of the scattering setting and the scale? I used 0.5 where you have 0.09.
I found the value of 50 through trial and error (best item to look at were the hands, I tuned the parameters until I got a slightly reddish effect on the fingers but not on the palm).
I read through your post and I agree that the color of "transmission" is crucial - with everything else same, this can give you anything from a yellow-ish ill-looking face through normal and towards a blushed appearance.
In the picture attached (DAZ Reby Sky model), I used a map for the transmission color (EC). I first tried to use the transmission strength maps (ES) as well, but then through that Octane would give me that though volumetric effects (material thickness), which I think is not available in the programs they made the maps for.

Yes, scale * scattering is the absolute number - however I found the absorption is also important.
For your render - the scale looks too small - since there is no SSS around her nostrils or fingertips.

I don't understand this. You say to increase the SSS effect, but if my scale is too small and I increase it, wouldn't that reduce the effect?
