How to check maximum page rank achieved for a website?

I have one website. I want to check what is the maximum page rank this site was having at any time.

Merely submit a "generic" search query at google.com using "generic" keywords found on your website [not your domain name or brand] and see the PR [Page Rank] of the website. For example, submit the following "generic" keywords -- sandwiches downtown los angeles [making sure to spell out Los Angeles which can easily be confused with the State of Louisiana which is LA]. Wait for the 16.1 million search results, then look at the No. 1 PR [nazos.net] which holds the highest [maximum] PR among the 16.1 million search results.
Good luck!
