Quoting myself, but the “active user” setting can be customized. 30 days is the default. Someone else said it’s 60 days here. If that’s the case, 3,400 active users - 800 new one-and-done/lurker/spam users - 2,600 active users. Apply the Pareto principle, and you get 520 really active users in a two-month period.
Most vB sites show a count of current visitors, and a list of members that are logged on. The default is 15 minutes. Some boards up the time to an hour, or even a day, so they look MUCH busier.
I’m not active here, like I am at the gym at 5:AM every morning. Granted, I can power clean 185, but I’m still working the Wendler program to bench press 1/10th of the weight of the fight against ignorance.

I’m not that active if I have less than 8k posts in nearly 20 years.
