If you roll dice sometimes the same roll will repeat itself. It's got the same probability of rolling Plan C each time. Probability is counter intuitive like that.

I didn't say their algorithm is flawless. But think about if you shuffle the tracks when you're listening to something on an ipod. Sometimes you will actually wind up listening to the same few songs over and over and so it has to be reshuffled. Bungie isn't sitting up in a room somewhere trying to decide what xur should sell, they just need to hit the "shuffle" button more often.

For sure lol
