Membership and event corrections in the MUIR era

Has anyone had any luck submitting a player or event correction in the MUIR era? Those possible yet?

How are you submitting event corrections? They should go to ratingsmgr@uschess.org.

Here’s a table by month showing how many events originally submitted on MUIR (ignoring ones from September and October) have had corrections made to them:

202511	107
202512	65
202601	72
202602	41
202603	2

Are they rating corrections or all types of corrections? Assuming 41 corrections were made during February 2026 and 2 during March 2026, should those corrections show up in our tournament listing at ratings.uschess.org?

I don’t know, they could be corrections that affect ratings (like results or player IDs) or they could be ones that don’t affect ratings (like the event name or TDs.)

There is no way to show what was corrected or when it was corrected. (That was true before MUIR, too.)

Are you sure? Logging DB changes is very common practice these days – I even ran into a case where the DBA said their standard was not to log for non-critical systems and they found out they forgot to turn it off – the Murphy Reverse Law - Mistake = Good Fortune.

I didn’t say it wasn’t possible, I said there’s no way to show it. The pre-correction records are archived, but comparing two sets of data (across 6 joined tables) field by field would be a bit time-consuming manually, especially for a large event, which is probably more likely to have changes made to it.

Yes, that’s the address I’m emailing. I’ll keep pinging them. Glad to hear it’s possible at least!
