| Nov 14, 2017 at 14:26 | comment | added | Myungjin Hyun | @Evargalo Thanks a lot for being so patient and explaining the whole thing clearly! Sorry it took so long to reply, your comment hadn't loaded until recently! Thanks again (+1), and I've accepted your answer! | |
| Nov 14, 2017 at 8:43 | comment | added | Evargalo | You are 2300 on Nov 1 (k=10). You win against another 2300 on Nov 2. Your Fide-rating is still 2300 but your live rating is 2305. You draw against a 2450 player on Nov 3. We calculate your gain by considering you are 2300 (not 2305), your Fide-rating is still 2300 but your live rating is now 2307. If you don't play anymore until Dec 1, your Fide rating at that point will become 2307. | |
| Nov 14, 2017 at 8:32 | comment | added | Myungjin Hyun | @Evargalo I'm confused: if they both use the same method, how are live ratings different from FIDE ratings? | |
| Nov 14, 2017 at 8:18 | comment | added | Evargalo | @HarryWeasley : no, the live rating websites use the Fide method, they do not adjust opponent's rating after each game nor each day. If you are 2300 and win 4 points on Monday, you are still 2300 for the calculations of Tuesday (not 2304). Two advantages: it is additive (if you won 30 points then lost 20 you will get +10) and it predicts the next published rating: your live rating on the morning of Dec the 1st is the same rating Fide will publish for you. | |
| Nov 14, 2017 at 5:36 | comment | added | Myungjin Hyun | And I forgot to add this: I sometimes read articles that say that a player gained x points or lost y points in some event. Does that refer to the change in the rating corresponding to only that tournament?(Like you stated in your answer: gaining 50 points in one tournament or losing 100 in another.) | |
| Nov 14, 2017 at 5:09 | comment | added | Myungjin Hyun | Just one more thing. I'd guess that the websites that publish the 'live ratings' use method 1? | |
| Nov 13, 2017 at 18:03 | comment | added | Evargalo | The classical way was to take it into account only after it has finished. There are some exceptions for long events like year-long team championships and a few top-level events. | |
| Nov 13, 2017 at 17:32 | comment | added | itub | What happens if a tournament spans more than one month? | |
| Nov 13, 2017 at 11:10 | comment | added | Evargalo | @HarryWeasley : yes, that's a step into becoming WIM / WGM / IM / IGM | |
| Nov 13, 2017 at 11:06 | comment | added | Myungjin Hyun | Um, I'm not well-versed with such terms...a norm is something to do with IM and GM titles, right? | |

| Nov 13, 2017 at 11:04 | comment | added | Evargalo | Absolutely. Also for calculating norms, btw. | |
| Nov 13, 2017 at 10:57 | comment | added | Myungjin Hyun | So for every match that month, your expected score will be calculated assuming you are rated 2300 throughout the month. The grand total of all changes plus your old rating adds up to your new rating next month. Right? A bit like method 2, but over a whole month? | |
