Ratings estimator

It seems the current ratings estimator has a glitch. Put in 3/3 from a quad, including a win against a higher-rated player, and it says you lost 8 points…?

This is the updated version, with the current revised k-factors, as of May.

I cannot reproduce this from the data given, please give more complete information.

This is the ‘new’ new calculator, with the recently revised k-factor.

Opponents: 1462, 1652, 1996 (the 1462 was provisional pre-event, if that matters.)

Score: 3/3

Current rating: 1979

Age: 48

Calculator says post-event rating is 1971. ???

Thanks.

When I put in those numbers but leave out the age, I get an estimated new rating of 2000. When I put something in the age field (which I believe should only affect an unrated player), then I get 1971. Doesn’t seem to matter what I put in that field.

I tried the previous estimator, and it does not do that, so something is broken in the latest estimator.

I’ll look at this when I can, probably not until Monday.

Thanks, Mike. You would think players over 45 would get “age bonus points,” not the reverse.

Now if they won’t let me in the U-2000 section on Labor Day I will point to the calculator.

I think the ratings estimator has been corrected. PM me if there are other problems.
