well you didn't show the entire event screen, nor the driver current states, but lets assume that device produces 10 types of events with a possible 5 values each, 10 * 5 * 1000 = 50000, I can't think of any other way of explaining this.
Please post a screen shot of that drivers current state...
But to your point, sure the more events in your system the bigger your database is going to be, that's where they're stored after all, and why I keep telling people not to create worthless events...
