We should get Devil to write Round #666!

Hello,

Recently I had just participated in Codeforces Round 654 (Div. 2). I submitted a solution for D at the last second (1:59:59) but it said "Contest is over" because the submit button has a 1-2 second delay. @MikeMirzayanov can you please add some functionality to have a small 1-2 second grace period after the contest is over for people who submit at the last second? I know I still have to get better but for some I think this would be very beneficial.

Thanks.

Hello,

I have been doing CP for almost two years now. Ever since I started, I assumed that doing CP would be similar to something like competitive math, in that all it takes to improve is to practice and learn the strategies and theorems. However, even as I did this for CP, I improved little. Can anyone who is experienced share how they improved? Anything would be appreciated. Thanks!
