I've been using the fact that my profile says "top 5% all time" as a bragging factor to demonstrate my knowledge to clients.
Now that I'm active again on the site it's started saying "top 2% this week" which isn't something I can put in a biography.
The actual question
How can I calculate the statistics all-time top 5% myself?
I've tried googling and found:
How to find what percent of X is Y: Use the percentage formula: Y/X = P%
So I tried:
my all-time ranking / number of users = % 19482 / 10652636 = 0.00182884311
Which is decimal form, so times 100 to get the percentage:
That's not 5%, so unless I've jumped a whole lot this month I've got this wrong.
Whatever it is, I'm clearly not getting into the top % of the Maths SE.
