[MENTION=101]ChibiKika[/MENTION], you make a good point.
Problem is that every verifiable use case you add to a thesis/experiment its complexity grows exponentially.

Just making general prob. math for this will need a dozen of us loading data for a month.
Taking different timezones, access levels, and player dedication would need for us to triple, or more, the amount of data gathering, and at least double de data collation part.

I have the same 8hs for sleep, and 9hs for work, with an extra 2hs of home<>office daily travel. And that doesn't take into account time for eating, cleaning the house, etc (I'm single).
The point about this kind of game is that you don't need to be logged in 24/7 (unless you're fighting for a high place in an event). You can log in every 2~4hs (depending on your level) and just burn the stamina.

That's another way I try to keep my data gathering the most sterile as possible: If I log in every couple hours and burn all the stamina regenerated, the data will be spread amongst as many spin-configs as possible.
