According to Valve's own "statistics" almost every player playing CounterStrike (97,800 of them) played every single minute for the month. Let's review the stats.
30 x 24 x 60 = 43200 minutes per month
4.217 billion player minutes per month / 43200 minutes per month = 97600 player minutes per minute. Completely impossible? Yes.
And don't even get me started on the dedication of the Ricochet players!
581000 player minutes per month / 7 players = 83000 minutes per month!
It's cute that Steam has a "stats" page, but don't make the mistake of taking any of those numbers seriously.
