So he played, before the 2010s, in 1986, where the rating list has him at 2110, according to MSA, he pulled a 2100 rating with no provisional and came back to playing, the existing rating gave him his floor before, but the first tournament back he dropped under 2100.
MSA shows 2100, from his previous rating
Yeah, but I donât see a 2100 post-event rating for him. Apparently he lapsed, but came back in 2018.
Weâre researching this one in the printed ratings supplements, if thereâs a record of a 2100+ post-event rating there, weâll make sure his floor gets updated, but that might take a few days.
Well he started playing after the gap between 1986-2012 he started playing again, not sure where youâre seeing 2018, has been consistent between 2012-present in playing. The main reason besides the discrepancy that I bring this whole thing up is that being such a prolific AZ player, many ratings had been impacted
We need someone at the office to research his pre-2018 history in the rating supplement books, my guess his ID is one of the ones that got purged in the 80âs or 90âs due to inactivity.
If he has a published 2100 rating from back then, clearly he needs a 1900 floor.
This is probably not the biggest issue on the staffâs plate at the moment, because once we get a floor in place, a rerate will solve any issues.
There are likely to be additional cases like that, because the old program was probably a bit more flexible in finding old floors.
Weâll make sure the membership department knows how to clean these up as they are discovered. Weâre planning to run the first rerate on MUIR soon, that may uncover several of these issues,.

May I resurrect my intermediate question? Sorry to pollute the main point here. After a March 2025 event, I reached a new high rating which then increased from the 2025 bonus recalculation. That new rating is correct in the crosstable
But it isnât correct as my highest rating on the graph is the pre-bonus update. Why is that? Doesnât much matter to me since itâs the same floor but players might not like it if their floor was set from 1899, not 1901
Thatâs because the graphs on MUIR are showing published ratings not post-event ratings. Unless a peak also happened to coincide with a supplement cutoff, the peaks arenât on those graphs.
Updating the graphs to use either published ratings or post-event ratings is on the task list as a post-launch enhancement, but I do not know when it is likely to be approved, worked into the budget, and worked on.
Thanks, Mike. Appreciate all your triage work.
Hi checking in for an update on this, given it hasnât been done yet
If youâre referring to doing the graphs based on post-event ratings, that isnât likely to be a high priority change to MUIR.
I suspect itâs this one:
I donât have access to the supplements, i assume Korey has access to a set in the St. Louis office. But his worklist is a lot longer than mine.
Iâve lobbied for getting all the old printed rating supplements scanned and posted online, but it got axed from the budgets I submitted as IT Director 10 years ago and I suspect nobody has championed this idea since then.
I still have supplements that go back to the 1986 super fat cumulative list. Send me the players info (name, ID, state, etc.) and I will see if I can find what is being looked for.
MSA now shows 1800 but also an 1800 floor, so the issue may have gone away with the big rerate.
Tim, the question is if you can see a 2100 rating for this player at some point that would justify the 1900 floor they used to have in MSA (but, I note, that they no longer show in MSA)
The floor for him used to be there, also his rating shows 2110 in the 1986 Jan supplement on the online PDF for chess life under Anthony J Booth
His first tourney in MSA (from 5/2012) likewise shows a 2110 rating, justifying the 1900 floor.
Yeah wild that he now shows only an 1800 floor in MSA.
With an ID of 1240xxxx, he would probably have joined in 1983 or 1984, so the big 1985 supplement should probably have him, but it looks like his membership lapsed and his member record was purged at some point. Apparently he rejoined in 2012.
ID is 12400817.
All the active tournament records for him show a floor of 1800, but those are generally computed from post-event ratings and his first post-event rating after he rejoined was under 2100. His pre-event rating (from some archival records that didnât include floors) was 2110, he SHOULD have gotten a 1900 floor back in 2012.
This is one that Korey will have to fix once we have membership corrections up and running, with an effective date of 1/1/2012.

Richard,
Attached are two files. One is the cover of the cumulative ratings supplement from 1986 (1983-1986). The other is the entry for Anthony J Booth 12400817. I did find another rating for him but lower than the one in the cumulative supplement. I found nothing after the 1986 Cumulative supplement. The *21 probably indicates a floor of 2100; however, I am not sure if the floors were calculated the same back then as they are now. I suspect those floors were calculated differently back then.
Is this what you were looking for?
Booth, Anthony J 12400817 0287 MA 2110*21
Good Chess,
Tim
