Probably a bug on Junior rating calculation

So after a long time (6 months) of waiting for a rated-for-all contest, I finally participated in yesterday’s February Cookoff! Despite being rusty and such, I still managed to get a positive delta!


Happy with my result, I scrolled down a little to see my Junior rating. Needless to say, I was slightly surprised by my spectacular performance when I managed to get exactly 1000 rating!

So either I have god-given talent to somehow get a -1313 delta, or the rating calculation has a bug somewhere.
Is this a record?

Same question, I’ve seen this on other profiles too, so it probably doesn’t have anything to do with your performance.

Thanks for reporting. We’ll fix this.
