At the user's info, there is a percentile status like
top 3% this year
Is there a way how to check other (week, month, quarter, all time) periods percentile?
You just need to do a little bit of math.
Go to the rankings page. Select whichever rank you want. I have selected Quarter Rank.
Now, note your own rank. Here's mine.
Also, note the total number of users.
Finally, calculate your percentile.
However, this is not the percentile that is shown on the profile.
If you look at the sidebar, you will see :
So, to find the equivalent percentile that the system uses, we need to correct for this. We need the total number of users having reputation greater than 200 which can be easily seen on the sidebar under Total Reputation.
So, now calculating the system percentile.
You could work it out... You can type a name in here to find the rank of a user. If you don't type in a name there are buttons at the bottom which allow you to find the last entry e.g.
Divide the rank by the total and multiply by 100 and you've got your percentage. Other tabs allow you to repeat this for week, month etc.
