That said:
Walton shot .505 from the field (RS) in the years he overlaps with Thurmond, but he's cited at .521.
Artis shoots .522 from the field (RS) in the year his NBA career overlaps with Thurmond, but he's cited at .598.
Parish ... .503, ... .533.
M. Malone ... .480, .490.
Maybe earlier guys flip the other way but I'm not sure about the methodology being as ... tight ... as it could be here..
I didn't run career data for each player *only for while they played against each respective center*. I presented career data for everyone, full careers ,for each.
If you want to do so, and present you research, please be my guest.
I won't because I'm not that invested in it. I thought constructive criticism would still be fair game though.

It's nice you put in the work and decided to share it but one can only comment on the visible end product.

If you want to open it for collaboration the simplest way would be to put the source data out there and anyone can interpret, scrutinize or iterate upon it, either in collaboration or independently.

Thank you- good catch. Noted, and, added.

Again, if you want to go through the rigor of breaking down exactly how many games a guy played "list as starting center"
So here the question would be do you want "list as starting center" or do you want Thumond's primary cover.
Unseld was typically the guy listed as center in Washington ... (though even if this is the criteria other players have guys listed [Lucas, Schayes] primarily regarded as power forwards).
Primary cover is much harder and might be unknowable. If I had to guess one I'd imagine he'd cover the guy shooting more (Hayes). But we don't
necessarily have to choose.
Including them both in the date isn't ... inherently wrong but the statement ...
"Thurmond held opposing HOF Centers to a .422 FG% across 524 games" assuming it is based on counting Washington with Hayes and Unseld games as separate games ... I would say is wrong. The game count as presented is wrong and credit is strongly attributed ("Shooting percentage of players I credit as centers is down to % in X player-games" would be a more accurate representation of what you have done, as I understand it).
Without the actual working - even the spreadsheet appears to be a copied output rather than one where calculations are active it's harder to check stuff.
The circa 15% reduction came out as 12.749004 on your original player list or 12.4497992 on with Russell. But that's using the percentage difference in your averages. And your averages
seem , at a glance (based on looking at the points averages to be
unweighted ... that is Parish's 2 game sample (or Gilmore's) counts just as much towards the sample as Chamberlain's 64 games. And without the working or knowledge of the precise number that led you to circa 15% it's hard to know whether that 15% actually came from a weighted average or whatever else ...
I
think the
career shooting percentages aren't shot weighted just an average of the averages (or else both times [before and after Russell's inclusion] came out coincidentally the same to the rounded to one dp version of what I got) but the versus Thurmond doesn't seem to be an average of the averages and so could well be shot weighted. This is good in terms of proper weighting but I think (and getting tired and low on time here) that that means that this is not a like for like comparison (career contribution to the average should be weighted in proportion to their contribution to the versus Thurmond sample, I would think).
As before (including a previous thread) rankings within NBA's 50 and 75 are not, to my knowledge ever made public. Thurmond comes 45th alphabetically among the 50 so I wonder if this is what you are referring to.
As before Thurmond is an exceptional man-defender and given his impact footprint is a very worthy candidate here (and versus a relatively longevity-of-quality weak Reed, would probably be my choice here, were I a voter).
