And, if people want to see the maximum number of events from their game, they can always check the game log every time they play and "do the math" to see when the next one is scheduled (yes, they are scheduled). I explained here how that works.

The scheduled event will be seen the next time the game is launched after the scheduled time. In all of my work with VV, I've seen the time between events be as little as 10 hours, so checking the game more frequently will help you see more events.
