Last week, the USCF announced that they will be lowering the bonus threshold from 12 to 10, and that they will be applying this change retroactively to all events in 2025, and rerating them. In the same article, it was written that the change should be done by Tuesday or Wednesday (which was yesterday), but it seems based on my account that the rerate has not happened yet.
I understand that because a rerate of every event from 2025 is a more significant rerate than one that covers just the previous week and some miscellaneous events. Does anyone know when this update and rerate is expected to complete?
Could you please link the thread here? I can’t seem to find it.
Also, I’m not sure I understand-- I have been following my post-tournament rating record since the announcement of the 2025 rerate, and 20 events and 50+ games doesn’t seem to have affected my rating by even a hundredth of a point, despite the fact that I played several players who have performed well above their rating many times throughout 2025.
You push the image that looks like a link below the post. Mike’s post seems unclear whether that was the weekly rerate or the “all of 2025” rerate.
I just got back home after being on the road for 10 days, as I recall the cumulative rerate back to January of 2025 was supposed to run last week, but I can check in the morning to see what was actually done in both last week’s and this week’s rerate.
Last week’s weekly rerate (starting on June 3rd) did rerate all the events affected by the bonus factor change from 12 to 10. Lowering the threshold increases the number of players earning bonus points, those who did not earn bonus points could still see minor ratings changes due to secondary effects.
For example, in the 2025 World Team, about 220 players earned bonus points in the last rerate of that event before the retroactive change, now that number is around 280. (The total number of players was around 1500.)
Also, I still think it would be good to put a link to the ratings estimator at the top of the US Chess home page under the “Ratings” tab like I suggested previously.
Also, the link to the “Rating System Algorithm” at the top and bottom of the US Chess home page needs to be updated to his version, rating.system.pdf
Since we shut down all access to the Joomla backend, where pages are updated or added, for security reasons, there are no planned updates of that ratings estimator page or any other Joomla-rendered pages. The plan is for both the www.uschess.org and secure2.uschess.org sites to be phased out once Leago is operational, as updating pages there is even harder now than it was before we shut the Joomla admin mode down and many pages there are very out-of-date.
Moving things like the governance archives to a new location will need to be done before we can shut those servers down.
I don’t know when there’s an equivalent to the ratings estimator planned on Leago, though it was mentioned in the RFP, I’ll put that on the checklist.
The Ratings Estimator has been updated to use the current bonus threshold of 10 and tested against a recent event where it was within 1 point in estimating the new rating for a player who earned a little over 30 bonus points in the event. That’s within normal expectations.
The link to the 2023 version of the Ratings Estimator was removed.
At the bottom of the US Chess home page, the link still says “Ratings Estimator (2023)” but if you click on the link it takes you to the 2025 version of the ratings estimator.
It would still be good if the link to the ratings estimator could be put at the top of the US Chess home page under the “ratings” tab.
