Board Game Arena

What do the numbers mean beside each player that have made it to the purple division on the Arena ranking list?

it's an elo-ranking calculated only for this season; it is always calculated, but revealed only when you reach the elite league - until then it is hidden.

Thanks, assumed it was some sort of elo, but didn't know why it was so different than the regular elo we have assigned. So I'm guessing this one must have an offset of 1200 or so...
