Not sure, so far it only seems like we have it plus @DollarsToDonuts. When there is a larger sample set we can infer what the levels define.
Since they are pushing it out slowly, it is probably just faster to wait for @christine to weight in on this.
Currently @MattJuniper is my stiffest competition, there is a 4 point differential. He is gonna give me a headache for the rest of the week 😛
I can only image the controlled chaos just before exams. We will be stressed and competitive.
