My question is has anyone ever given a grit rating to strops?

Hones and pastes have a sharpening or polishing effect on a razors edge and all of these have some kind of grit rating. Stops also polish the edge so therefore I was wondering if a grit rating had been given to these, as I have never seen one. I realize that there are different types of leather out there that give a different draw feeling to the razor when stropping so let's pick on Tony Millers #1 strop, what would be a good grit rating for this strop? If anyone wants to chime in on some other strop please do so.

The reason I am asking this question is that while using say a 0.5 micron paste, which I THINK has a 50,000 grit rating but can't find the post that gives grit ratings, I was wondering if this is finer than a strop and then when I use the strop it may have a grit rating of less than 50,000 and may unpolish the blade a small bit.
