That's fair, but it's also fair that human users aren't the only users that we actually care about on nostr. DVMs are users. Servers are users. And yes, even bots are users. This is more of a question of what do we want to measure vs are these numbers correct.
Would love to talk through this more sometime though because I'm sure there is some fun stuff we could do to build a chart that would allow us to visualize these breakdowns better.
