welcome to the rabbit hole ;-)
CS owners seem to want to find some sort of "conversion" that they can apply to their meters.
I think if you didn't read them the posts by ETC901 are worth reading

actually after you read that you should go to the start of the thread and read it all (if you didn't already read it)
I know that some people here (lets call them idomatic types) say "none of us here are doctors" .. well except for the ones who actually have doctor in their fukken name
how would you know who's what?
The answer is we do actually have doctors here, further we have people who are not called doctors generally because they are specialists in a field. Further we have professional researchers here.
So when I say ETC901 knows enough to know what he's talking about I say that from the perspective of having worked with him in helping him start on my INR management system. I know what he does, I know I respect him.
Personally I don't have much respect for the CS product.
