Scanning through standings, I saw something strange: Link

Why is it rated for him? It's a Div.2 round but his rating is over 2100.

I think the reason is that the registration of Codeforces Round 593 (Div. 2) was earlier than the rating changes of Codeforces Global Round 5 (he also participated in Codeforces Global Round 5,) and he registered before the rating change. If that is the case, please fix the problem, since it is pretty unfair for him (he lost his Master title in this contest.) Thanks a lot.

[UPD] Just curious, if a contest's registration is earlier than another contest's rating changes, does the latter's rating change affect the eligibility for the former?

If no, it seems that the same thing will happen again...
