The outlier in Perth is due to a SE (Maddison Inglis)

A combination of things:

Tamara Zidansek is the first case, in the data I downloaded, she has two lines of data, one as a seed, one as a non-seed. She should be a seed, I've deleted her non-seed line, and adjusted the chart.
I didn't conceive that this duplication was a possibility. I've checked for other duplicates with some formulas, but can't see any others.

Fiona Ferro is the second case: Was 285 at time of the seeding, but 248 in the rankings produced after the seeding was made. So, her ranking at time of play is correctly as shown.
She just got unlucky, and Melanie Stokke, the eighth seed, got lucky to hold on to that spot.

Here is the updated Curitiba chart with the Zidansek situation corrected

There is a debate to be had over whether the chart should show the ranking upon entry, when the seeding was made, or when the matches were actually played.
I wanted the latter, as those are the rankings we would use when we quoted CH best wins, and seems to me to more isefully reflect the true strength of the field.

I'm guessing that the rankings are current rankings, which aren't the ones that seeding is based on. Fiona Ferro is WR285 on the acceptance list, but currently WR248

Edit - Got distracted on the phone, so posted late !

Phone call aside, you had the answer before I did

Is this ranking page any good?

openerarankings.com/

It seems to have dates of birth and be in one long list - there is an ATP and WTA page. May not be what you need but it is one I just came across?

 Nationality is in a picture rather than text: that may make it tricky to use if country is a discriminator.

Yes, I'd have to run a lookup to match the names against another list, to populate the nations, which is not ideal, but is better than what I currently do.
But, you can output the entire list from 1-2000 in one go, which just about makes up for that, as exporting one file each week to sweep for new additions isn't too bad. The data doesn't paste in raw form too badly either, it's pretty useable right from the get go.

There is some great data on this site, and great functionallity, it's just laid out really badly, which is a shame, as they're selling themselves short by their presentation.
For example, if you dig in to the individual player breakdowns, you can see all the entries, when they drop, what needs to happen for non-counters to be eligible, how uniform the players points distribution is (are they week-to-week consistent, or dependent upon a few massive scores at big events) and how that compares to other players, and so on.
All really interesting, and useful stuff, with loads of options to tailor results when you figure out what's there.
An excellent find. Thanks

 my pleasure , glad to help. To be honest all I did was Google tennis rankings with dates of birth or some such and up it came!
