Hello,

I have just noticed that many people (including me) have different contributions listed on their profile pages and on the top contributors list. For example, currently, on my profile, it says that I have a contribution of +16, but on the list of top contributors (http://mirror.codeforces.com/top-contributed/friends/false/page/5), it says that I have a contribution of +15. What is the reason for this?

Some more users that I have noticed with different contributions on their profile and on the top contributors list as of now are Petr, Lewin, and Edvard.
