What does a question mark (?) next to my rating mean?

When I inspect a rated game of mine, I see:

Unihedron (1156?) +49

What does the question mark next to my rating mean?

(Note that, when I hover on my userbar, it also shows a question mark for the variant games.)

The question mark means the rating is provisional.

Concretely, that means the glicko2 deviation is superior to 110. The deviation is the level of confidence the system has in the rating. The lower, the more a rating is stable.

More games generate better rating stability, unless the rating vastly fluctuates.

TL;DR: Play more games and the question mark will disappear.

Hey Thibault does that also mean you gain/lose less elo per game?

110 deviation in bullet, but still ? in profile.
so you change the maximum number again, right?

I don't know. maybe it means that you've played only one or two variants.
