Any attendance figures derived from "zoom" meetings are at best extraordinarily inaccurate, and probably little more than wild guesses.
Depending on what platform you are using zoom on, you can see only between 4 and 25 participants at a time.
Each "participant" (connected device) might have one, or 2, or 6, actual physical people watching & listening.
So for a meeting with say 200 "participants", you have to scroll between at least 8, maybe up to 50 screens, looking at postage-stamp size images & trying to count how many actual people you see.
Oh, did I mention that participants frequently "jump" across screens? You might be looking at gallery view screen 2, and by the time you get to screen 4, half the people who were on screen 2 are now on screen 4. Some of the ones who were on screen 4 are now on screen 3, or screen 6, or screen 1.
Not to mention all the participants who turn off the video camera of their own connection. So maybe there is one person there, or maybe 6 - you can't see it.
Oh yeah, there are also folks with outdated technology who can only listen to the zoom meeting, video does not work. How many of those are there? Who knows?
So if you hear that "we had 225 at our Memorial", trust that the actual count was probably somewhere between 120 and 180, and no one has any idea what the real number was.
