The Pro Rank™ now factors the Lodestone achievement history for each player. Each achievement has it's own score which is always subject to tweaking. To find out how much points each one is worth check out this page:

You will also noticed "attained" column which represents how many chars have the achievement divided by the total chars. We have at this time, 458,121 characters in the database. This has no effect on the score but does help determine how difficult, time consuming, or just unpopular it is.
I came up with the scores with the counsel of some experienced players but I arbitrated the actual number.
Ranks are recomputed every 30 minutes. Characters with a physical level greater than or equal to 20 are considered into the ranking.
Some users asked to have an option to hide the rank from the player and linkshell page. I will add this preference soon and will post about it when I do.
I will give registered users the ability to manually update their Lodestone achievement history. I know many are out-of-date. :( Updating the lodestone history is more intensive on SE's website because it requires several requests to fully scan one character. I have to carefully consider how I go about doing it.
