Recently, registrant counts for Codeforces rounds have been reported incorrectly on the Contests page. For example, at the time of writing, Codeforces Round 911 is listed as having 2162 registrants:
Clicking the 2162 number to access the list of registrants, however, shows that only 302 people have actually registered:
Indeed, the registrant list indeed only contains 303 names, including one participant who registered while I was taking these screenshots :)
The same bug applies to CodeTON Round 7, which currently reports over 10,000 participants on the contest list but lists fewer than 8,000 contestants in its registrant list. Obviously, contest registration statistics are not a critical feature of the site, but even so, I wanted to make sure Codeforces staff are aware of this issue since I haven't seen anyone else report this bug yet.
