I just took a look at the first page of site's users, listed by within-month rep count:
While the names seem comfortably familiar, the rep point totals for many of the users seem high -- impressively high, in fact! So high, actually, that they seem off. E.g., how come that @egreg, far and away our most productive contributor, is only in fourth place?
I then calculated the actual month-to-date totals:
shown actual
Werner 5375 1605
ulrike f 3348 775
gonzalo m 3048 978
egreg 2530 2530 *
leandriis 2263 405
bernard 2168 715
moewe 2055 715
david c 1765 1765 *
mico 1647 1647 *
zarko 1583 1583 *
phelype o 1449 125
lockstep 1430 440
As you can see, I was able to obtain a "match" between the reported and actual totals for only 4 out of the 12 top-ranked users; the matches are marked with an asterisk.
Questions: Is this discrepancy something that should give us cause for concern? And, is this issue specific to TeX.SE, or is this a bug that affects all StackExchange sites?
