History versions: here, link from Luogu. If this project is successful I'll make a similar table for Luogu.
This is someone else's watch. Due to the exclusion of interfering factors, the persuasiveness is stronger. (But I will still insist on making this less convincing version)

The columns: name = name, min = min, max = max, total = there're how many people in front of this line, current = there're how many people with you in this zone, proportion = proportion. Guess where you are?
I made this thing purely out of boredom, and it would be my honor if it could be helpful to you.
I hope I will remember to update it every month.
Fun Facts: - Due to the strange api of Codeforces, I think the best way to make a table (which really has reference value) is to go through the whole ranking myself. So the CodeForces table includes all of the "users participated in recent 6 months", and the Atcoder one includes "users participated in a rated contest in recent 2 years". Sorry about that.
- The number of people in the hundred-point-zone ranging from 300 to 400 is the highest. As long as one participates in a competition and submit an WA code (which get 0 point), most people will get stuck in this place. (I tried to avoid this problem, but I'm too naive. Stopping such people getting into my table is like squeezing water out of flour)
- AtCoder has a different rating system than CodeForces. This system does not give you extra points in the first six competitions like CF, so the most concentrated zone of their ratings are from 0 to 99 points.
... - I get a purple cm yesterday while I was celebrating my birthday.
Many people only registered for only one contest. At the same time, inevitably, alt accounts were also included in the statistics. So this statistic is only for entertainment purposes.
If you are willing, you can write down your current rating and goals below. Encourage each other to promote enthusiasm for effort!
