Feature Request: Display performance rating alongside rating change

Hi everyone!

I think it would be better if Codeforces displays contest performance rating along with rating change, similar to Atcoder.

+46

I honestly want this to be implemented directly on CF. Carrot can't be precise due to CF not providing real rating used for calculation (before 6 rounds of participation), and is often unstable. For prediction purpose, okay, real-time prediction is likely to be too much for CF server, but I'd like to see at least the final performance data officially provided by CF once the rating is updated.

Realtime performance shouldn’t be an issue either, CodeChef does that with 45k+ participants in every Starters.
