Site stats regarding And YOU Get A Hat!

The “Group size” column tells you how many of the site's users it took to unlock the 20 necessary hats. In other words, what was the smallest possible group of users that would have unlocked the hat all by themselves, if nobody else had had netted hats yet at that point? This number is indicative of how much of a group effort it was for the site to unlock the hat. If the number is low, that means “one-user-armies” – few users took on a bulk of the hat earning. If the number is high (the theoretical maximum being 20), it means it was a collective effort.

Please note that this number is an approximation. Finding the guaranteed minimum group size is an NP-hard problem, so it is possible that the actual number could be lower. (If you're interested in the details: The set cover problem on Wikipedia. We're using the greedy algorithm described there.)

The “Highest hat count” tells you how many hats the best user had unlocked on the site at the time And YOU Get A Hat! was awarded (not including that hat itself).
