I recently was awarded the "Mortarboard" bronze badge. It's for earning more than 200pts in a day. Turns out I had done this in the past back in October of 2011.
Is this a new badge? Is the algorithm only applied from the point of implementation forward? Just trying to understand how this works...

I don't know how long it's been around, but it's not a recent change.

Looking at your reputation history, the 2011-10 day when you earned more than 200 points wouldn't count because 100 of those points were an "association bonus".

Reputation points earned for associating accounts or for accepting other users' answers to your own questions do not count for the [mortarboard] badge.

See List of all badges with full descriptions for more information.
