How do we measure when evaluating Mycorrhizae concentrations?

I'm confused. Do we consider just propagules per gram? Or does the percent inert ingredients need to be accounted for?


Here are some sample labels.

Dynomyco: 5% microorganism but 900 propagules/g

Myco Bliss: 2%? And 1000 propagules per gram.
