Vladimir Barúmov (2836021) earned a 5.0 and a 7.0 in his 2 official games, yet his average rating seems to be 6.5. Where's the catch?

And, while we're at it, I've seen players who have played a game with less than the minutes required for getting a rating, who still get an average. Is this a bug or a feature?

5.0 and 7.0 are rounded, so it looks like they were rounded down in that case

Unless I'm nuts, there have to be different rounding algorithms in place for the game rating and the average rating...

If it's rounded to the nearest rating:

5.24 + 7.24 = 12.48 ... /2 = 6.24, rounded down 6.0

If it's rounded down to the nearest half:

5.49+7.49 = 12.98 ... /2 = 6.49, rounded down to 6.0


Unless the average is weighted per minute... did the 7.0 game have more minutes played?

EDIT: Yes, 11 minutes at 5.0, and 26 at 7.0. So it looks like the average is weighted by minutes played, not just a plain per-game average. A happy surprise, IMO, although it's a bit counterintuitive to have a different denominator for just one number without telling people.

I thought about this option, but then I'd be surprised that it is displayed with a .0 in the end. I'd be much happier if oueflette is right
