The formula, found in the FAQ, "Win Expectancy = 1 / (10^((OpponentRating-YourRating)/400)+1)" indicates no rounding. Therefore rating is calculating with decimals, but shown as integers.
Just because they don't mention it, doesn't mean they don't do it. My guess is that they do round to the nearest integer.
And I also think that the difference between the 'real' rating and the rounded one will be only a few points (once you have reached the rating where you belong).
But if some mathematician could share some proof with us, I would be interested.

Originally posted by nilocthe 1/2 point error is nothing compared to the error of constantly playing and losing against higher rated players than you. Your rating is also a provisional one right now and is calculated differently than normal. Wait until you have finished over 20 games and check again.
I've noticed a slight calculation error when tracking my own rating. The difference between my rating calculation and RHP's is only one point (at this stage).
Is a person's rating truncated to be a whole number? That, which is displayed. Or, are there hidden decimals that we don't ever see, and that get included in one's rating, and calculated against an opponent?
Kind of like that 1/2 penny in Jumping Jack Flash, with Whoopie.
Originally posted by nilocYou definitely have a point. Small differences add up.
Besides, roundoff errors can have huge impacts in real life.
I heard a story about a computer hacker who had a high-yield savings account and managed to round up one of the 20+ decimal numbers in his interest percentage. Turns out his money skyrocketed, and he was arrested, despite the fact that he had only rounded up such a small amount.

I belive the concept of 'skimming' points is more then a mere fabrication. I have frequently played a series of blitz games against someone of a similar standard and we score 50% in the matches but end up with both our ratings going down.
I am sure there is some greedy fat cat somewhere who is hoarding all those points.
Originally posted by FabianFnasWhy do you say that it seems your assumptions are right? I didn't hear any evidence for it ... yet.

And even if it turns out to be right, I still think it qualifies for being called naive 😀
