I know well why the review-counter sometimes does not show a number that matches the sum of the review tasks I could do.
Yet, lately, I noted that the review counter (for 10k+ users) is persistently around 60 or higher. It changes, and if I enter the reviews there is sometimes something to review, but it is nowhere close to the number it displays.
At first I did not pay much attention to it as I thought maybe I had just skipped a lot. But since this persists since some time and a similar observation was made by others, I wanted to bring it up.
Did something unusual happen and might there even be something broken, or is this just a quite strange coincidence for me and a few others?
A direct way to decide this with some confidence would be if somebody with 10k+ that usually does not review (or at least did not review the last days), could just visit the review-page and report if for them the numbers are roughly matching.
Added: Following the answer, it seems that indeed the review counter in the top-bar does not match at all the actual number of review tasks lately.
I stress this is not some small fluctuation but about a difference of around
60 130 that seems persistent since quite some time (many hours), while the counter does change (it might be too high be a fixed amount but it is hard to tell for sure).
