Problem: Because different users are active for a different amount of time, it’s sometime hard to estimate which users are more active purely based on the amount of edits.
Proposed solution: There will be a new line in Special:CentralAuth called average edits per day. It will take the number of edits done globally and divide it by the number of days the user was active. This doesn’t mean the amount of days that passed from the day the user created his account until today, but the amount of days that passed from his first edit till his last one. Also, there will be another line telling the average amount of edits done in the last year/month/6 months.
