Some not unexpected startup issues for the first rerate and supplement run, they’re going to make another pass at it overnight and we should have the supplement files to check for accuracy and formatting tomorrow morning.
This will mean some events rated today make the December list, but I believe the plan is to only look at sections that ended on 11//19/25 or earlier for inclusion in the supplement.
With luck the December rating list will be out Friday afternoon.
Thank you all for bearing with our startup issues.
BTW, because of the major database changes made in late October and some corrections to the ratings algorithm programming uncovered during testing with Leago, this supplement list will be much larger than normal, possibly over 300K players, but most will only see a ratings change of a few points.
I think that’s being addressed but I don’t know if it is done yet, try refreshing your screen.
One major CCA event got messed up during a staff correction and that may cause a little rippling when it is fixed in the next small rerate before the next attempt to generate the December ratings list.
Otherwise, the rerate seems to have run properly, though the ‘more’ tab isn’t showing them in perfect reverse chronological order yet (it appears to be sorting them in section number order rather than reverse section number order), which has been reported. I was able to trace the ratings flow from one event to the next, though.
ok, the rating on the individual player page is back to the November rating.
We do have at least one tournament that is not showing up on the “more” tab. The ratings on that page still appear to be correct, it just skips that event. The associated rating jump is correct, just the event is missing from the list:
The generating of the December Rating Supplement Records is done, we should have download files to test soon.
One issue I have noted is that if a player does not have any ratings data in the current month but had a prior rating, the ratings fields are null for that ratings type in the current month. I don’t know if that will be a problem for pairing programs or not, it may be something that can be corrected when generating the download files.
That’s what’s in the database, that may not be what we want to show in the download files, though. There are some advantages to showing that a player had no activity in a given month, but this doesn’t necessarily show that if the only change was due to rerating. FIDE gives a game count, and that’s a good idea, one we may want to use.
For the moment, I’d rather get the download files built and available, we can always tweak them later on if this causes a problem.
You can watch the supplement record build process on MUIR as it moves along, something I’ve often done for the last 20 years on the legacy system.
I’ve not seen any noticeable errors in the data from the final rerate, so I assume the supplement download files will be good to go once we know the files are valid.
We have, of course, already received one complaint about a player who missed making the next rating class by 1 point, but as far as I can tell the formula was correct.
There appear to be problems with reporting provisional status and game count in the december supplement data, we’re looking into it, in addition to the ratings flow issue that suggests a problem with the rerate itself
I do not know if these problems can be cleared up today.
It does look like they’ll have to redo the supplement generation which takes about 6 hours. There will also need to be another rerate, and there are a couple of issues related to that which need to be checked out.
This is why I was hoping for 4 weeks between cutover and the next supplement run, to find and fix issues like this. Pushing the cutover into December was not an acceptable option, too.
My understanding is that there is an error that is causing some sections in which a player competed not to appear on the ‘more’ page causing a gap in the flow of ratings from one event to the next. They’re working on fixing that. But the supplement data is correct.
Korey tried to load the 2nd version of the gold master file into SwissSys. First it complained that the file name was too long, then it just hung. We don’t know if that’s related to the file name issue.
If people would like to test these files with a pairing program, please email me, teling me which pairing program (and version) you have– mnolan@uschess.org. Note that these files DO have data issues with them so they cannot be used for pairing or other purposes.
I do not have an allratings tab file to test at this time. My understanding is that this is the only upload file the current version of WinTD supports.
As a heads-up, we’ve got some data inconsistency issues between MUIR and the membership system that may make it difficult to exclude some records from the Gold Master files that we have not included in the past.
In the interests of getting this data released, we will probably just leave those records in. If we can resolve the inconsistencies we might create new upload files later on, but otherwise we’ll just try to get it solved for the January files.
