Mushrooms have so much variance that giving range like you did is almost impossible.
During my youth, I had strong trips with .5g and meh one's with a few grams, sure it's not the norm but it's not an exceptional occurrence either.
My experience told me that the stem of the smallest mushrooms are a lot stronger than those of the bigger one but that an heuristic not an hard rule.
If I wanted to microdose psilocin (for which psylocibin is a prodrug), I would order 4-AcO-DMT¹ fumarate (another prodrug for psilocin) from a reputable Canadian chemical supplier. It's almost identical to mushrooms, the difference being that it is predictable and somewhat easier on the digestive system.
