The other day, after manually imputting results for an online event (the dbf files are not uploading properly, which we’ve already passed along), I was surprised to see that the tournament was rated under the Dual (OTB) system, even though I had turned on the “Online” section slider for each of the sections.
Since then, I have rated several other online tournaments, and have noticed what seems like a bug to me: when you are first asked to select a time control (I entered G/25;d5), the page then says “Dual (OTB) at the top. Next, when you click the slider to specify that it’s an online tournament, nothing changes. It keeps the tournament rated under the Dual (OTB) system.
If, on the other hand, I turn on the “Online” slider BEFORE I enter the time control, then once the time control is entered, the tournament will properly display as an Online Regular tournament.
It appears to me that currently you MUST turn on the online section slider before putting in the time control, otherwise the tournament will be rated as an OTB event.
A secondary question that I’ve emailed Korey about is whether or not it will be possible on the USCF’s end to change the one tournament I’ve already submitted and was incorrectly rated as an OTB event, to an online event, or whether I will need to re-submit the entire tournament again for rating. Thank you.
Could this be something to do with time controls with a delay aren’t currently possible on any online server I’m aware of? Are you sure you’re submitting the correct time control for these events?
Just an update, the tournament we rated as an online tournament is still incorrectly rated as an OTB event. I’m not sure if the 20 events that needed to be corrected after the developers made a fix have been fixed yet or not, but if so, our event must not have been one of the 20.
Are all rerates done from “time inmemorial" (late 1991) to the present, or do you have some other set “good enough” date like the previous week or month that is typically used?
I don’t know exactly how it will work on MUIR yet.
On the previous system, the rerate window was set as being any event that was initially rated on or after 1/1/2004, including around 2000 events from 2003. I believe that will also be the rerate window on MUIR
On the previous system for most weeks we would only go back as far as there were new or updated events in the system, anywhere from a couple of months to several years.
Once a month, ahead of the supplement run, we would run a full rerate back to 1/1/2004. That would pick up any changes that came from membership issues, such as changing someone’s birthdate which can cause their initial estimate for their first rating to change if they are under age 26. That’s also when it would pick up adding someone’s FIDE ID, which could also result in a change to their initial estimate if they had an existing FIDE rating at the time of their first US Chess rated event.
I’m not sure exactly how all that will work on MUIR yet, they may be planning to do pretty much the same thing.
The Ratings Committee prefers to keep the rerate window where it is rather than move it forward, shortening the window. The early plan, back in 2005 or 2006, was to move the rerate window forward by 12 months once a year, but over time the RC decided not to do it that way. The downside of that is takes a lot longer to rate over 260 months worth of events than to rate a couple dozen. This did not really become a big issue until 2014, when we went from storing ratings as integers in between events to storing them in floating point. Floating point ratings change a lot more frequently than integer ratings did. In most months prior to 2014 perhaps about 5-6% of the players would see a rerate change. In the months since 2014, it is not uncommon for 90% of the players to see a rerate change, though usually it is very small, like .001.
But floating point inter-event ratings, like rerating itself, solves more issues than it creates.
