# Top xx % this week/month/year percentage meaning and why it didn't write the rank (than percentage)?

What is the meaning of the percentage of top xx% this week/month/year? I know if I click the top xx% this week/month/year, I will be directed to the user reputation leagues.

Why it didn't write the rank of the week/month/year than percentage? I think it is better to write the rank than the percentage.
