The update in PR was from the corresponding jumps I saw on my search keywords in google webmasters as well as actual PR. I saw 0 in december/january, and then noticed a jump of search rankings in feb. In late march my page rank was actually observed as 3 and then in april around the 6th I saw that my PR was reported as 4. Which was accompanied by another jump in my keyword rankings. Update - I put a note at the bottom of the article to better reflect how I got the numbers.
