No, it is not a bad metric, it is only ONE of the metrics.. It's a question that needs to be asked. Are we short of the revenue producing number, close, or over it?
It's a simple, single question that is one of the first questions to know once something rolls out. If they cannot sign up enough stores, then it's done before it gets started.
Just one of many pieces, a simple question, and it is important to know that they are signing up more and more.
Thank you for the additional questions here, too.
