How can overall total ranking and overall ranking for live games be different (in this case)?

This would be the relevant ratings update thread/quote I suppose

@anoek

Speed and size specific ratings

It’s been a known issue that you can’t really compare the different ratings on your profile. Your overall rating had pretty much nothing to do with your live 13x13 rating for instance. This is because they were computed using completely independent rating pools.

@flovo came up with the great idea of using your opponents overall rating when updating a sub-rating, this has the effect of the rating pools converging into the same scale as the overall rating pool, so the individual ratings should be somewhat comparable now.

@GreenAsJade

I believe that we expect overall rating to be different to specific ratings, for the reason I gave.

Sure, but not for one game like in the example I provided, and likely not when a player has only played one category, one boardsize with one timesetting only.

@GreenAsJade

However, overall rank is not supposed to be “some kind of calculated average from the other ranks”, it is supposed to be “the rank that you get when you include all games”.

Of course, I’ve also commented something to this effect in many threads, and that’s not what I’m commenting on or disagreeing with in any way.
