Weird rating thing

ABOVE:

I won two Blitz games today, winning like less than 10 rating in each one. It says I have gained 79 rating. maybe cause i joined the Blitz shield when i was 1786, is that the reason? kinda weird

PS, i don't really care. it looks like i won 2500s

Weird stuff indeed. Prolly a sweet bug you've got ::)) well done

Precisely, that's the reason.

Might want to not sign up to tournaments days before, to avoid this confusion.
