As noted in T300075#10974401, it seems that there are two different methods in use in CentralAuth for calculating a global edit count, and that's why the discrepancy appears between UserInfo and Special:CentralAuth.

If it helps, take a look at T313900 - I believe that this issue is related to username changes, with one of the edit count calculation methods presumably counting a user's pre-rename edits twice.

I renamed my account back in 2022, and I've been affected by this problem (hence that other issue), and it appears that User:Bosco Sin and User:Paloi Sciurala changed their account usernames as well - and have been impacted by the same problem as myself.

Anyway, it seems that the CentralAuthEditCount.getCountFromWikis(CentralAuthUser $centralUser) method does correctly calculate edit counts, but the overall CentralAuthEditCount.getCount(CentralAuthUser $centralUser) method doesn't (I suspect that the problem may be within CentralAuthEditCount.getCountFromDB( IReadableDatabase $dbr, int $userId )). No idea how to poke around with that myself, but I figured I may as well say something to help you to narrow things down a bit.

Thanks @HotMess!

I agree that we should make use of getCountFromWikis() to resolve this task.

Since T313900 is about to be fixed, you could probably revert your workaround, which is really slow (getCountFromWikis() has to query every local wiki's database where the user exists).

This is now filed as T401708, so I guess this task is done.
