I'll post back with results from that timestats thing, just got a ps3 so I'll hopefully be on less, although it's not like video games are better, but I've also got my final exam on monday, which means I should be on less, although it's far more likely I'll just end up on it more.
Not sure if you added me or not, don't think so, but I don't really get the ps3 yet, It sucks compared to an xbox message wise, but the price is nice.
also I'm incredibly glad you don't get that tracker thing for mobile, & it's good how it tracks how long you're actively using it rather than how long it's open.
Not sure how it's tested, I'm on a lot more than 4 hours a week, maybe it's time spent actively using it, typing/clicking? Idk, either way here's my results if anyone cares
