Have followed ISN loosely and have been doing so,e research to understand the evolution of ISN from a Micro Cap to something more established as it is today or put another way from 5c to 80c

I'm sure though I've misunderstood the company so looking for some pointers here

Am I correct in my assumption that the Wheezeometre creates revenue by one off sales? How much reoccurring revenue is possible from subscriptions to the program?

Also 1% penetration will result in $7.5m in sales
This seems low for such a large market cap so I'm sure I'm missing something here
