As of the last day, there was an undisclosed rerate, which contradicts the bonus threshold lowering to address deflation recently. Any explanation?
We’ve been testing the rating programming on both the current system and the MUIR test system, and found some programming bugs that have been corrected on the current system ahead of this final rerate on this server.
Update: My bad here, I made what I hoped was a minor change but I blew it, and it started affecting ratings in a big way starting in December of 2007.
I’ve stopped the rerate, fixed the bug (I think) and am testing the code carefully to see if it works. I think it does.
I have restartedt the rerate back at December of 2007. Everything should be fixed by tomorrow afternoon. Thanks for bringing this to my attention.
Thanks! I’m surprised it hadn’t come up. I noticed it hugely here in AZ because a particular player I know started off with a non provisional 2100 and originally had a 1900 floor, but it dropped to 1800 and with how many games played, it made some waves
We did test both the data corrections and the corrected formula coding on our testbed server and over 3/4 of players will see a net change of under 2 points, about half will see no change in their rating expressed as an integer.
But I broke protocol on the fix I tried to make yesterday, and that was a dumb move on my part.
The good news is the corrected code passed for 100% of the affected events, and the restarted rerate is almost through the affected months (December 2007 through August 2012), though it will take a while for MSA to get updated to reflect those now-corrected ratings. MSA updates are always done in descending date order, so that any new events get updated first.
