##Disclaimer

My question **isn't** about how often the FIDE ratings are updated. I know that's done once a month.

---

Are ratings adjusted match after match, or after every tournament? Even if the ratings are updated once a month, does FIDE count every match, or a whole tournament?

##An example to make my point clear

Consider a three-player, single round robin tournament.

**Player**                  **Elo**

Roanin Novel          2798

Rigi Hains                2745

Dan H. Yvasin            2784

#Results

**Round 1:** R. Novel (1) beat Rigi Hains (0)

**Round 2:** Rigi Hains (0.5) drew with D.H. Yvasin (0.5)

**Round 3:** D.H. Yvasin (1) drew with R. Novel (1.5)

##My question

If FIDE was calculating the players' ratings, would it first update the players' ratings **match by match**<sup>1</sup>, or would their rating be adjusted by **counting the tournament as a whole?**<sup>2</sup>

<sup>1</sup> In this case, rating changes after every match.

<sup>2</sup> I mean we calculate the expected score of each player at the start of the tournament, and compare it with the **final score only.** No rating changes occur between matches.
