Advanced Gauge licensing & usage

Good Morning,

I’m interested in buying ADVANCED GAUGE but I don’t understand the pricing model well.

At the moment I have a report with a dozen of ADVANCED GAUGEs displayed online only by ONE user; in this case the number of licenses to be purchased corresponds to two, correct ?? one for the developer and one for the viewer user.

So, I can think to buy (for example) 20 licenses and have 19 different users (or reports?) viewing my reports?
