Sorry...

do you want to specify in the URL all data you want to be show in the statistics page?
Then how would the page be useful, if you need to know the values before open it?
Does not make sense for me...

If a function be wrote to read the data from you database,
there's no need to inform anything in the URL.
You open the page, and the data is show (the SQL queries run in "background").

If you want a single page to centralize the data from 2+ boards, then I see more sense:
You want a custom page that will inform the data based on what you inform in the URL.
However, still not the best way, unless it's for personal and not public visible.
The better is still read it direct from the database.

Let me know your real intentions, please.
