What the heck is a "standard" rating on Chess.com? The site doesn't seem to include such a thing.

Don't want to put a spanner in the works, but I played three 15/10's and they all got listed as rapid. I'm here seeking the same answer.
My bullet rating go from 800 to over 1000 for the last 4 days. But i can't seem to get my blitz over 650
Sorry if I'm asking a dumb question, but every discussion about ratings on chess.com includes some mention of a "standard" rating. Chess.com help section clearly states that there are 3 different ratings on the site: Bullet, blitz, and rapid. What is everyone referring to when they speak of their "standard" rating? Is this daily chess? If so, how do you find your rating for that?
