Why Does My Page Rank Change Twice A Day?

First, let me preface this by saying that if I were on the reading end of this post, I might think that this is some cheap ploy to get traffic. Please be assured that this is certainly not the case, and I hope to prove it with your responses. That said, I have an interesting question (well, interesting to me anyway).

I keep my IR (although I realize it's in my signature, I don't want to even create link website link here so as not to get anyone bent out of shape) website as my home page and I will either work on it or monitor it frequently. I work mostly in the Resource Center or the blog, but never the front page and I don't work on the site daily.

Now the question; I've noticed for the last couple months (yes, "months" and I didn't think to ask anyone until now) that according to my Google toolbar, my site's PageRank reads as a 4 in the morning and a 5 in the evening. Again, without any changes to the front page, and it will even change during periods of several days without changes anywhere in the site.

Does anyone know how this can occur? I'd also like to see if anyone else is experiencing the same results (and this is where someone might be skeptical about me trying to drum up traffic. All I can say is 'no' and there is nothing on my site that provides me credit for impressions or anything like that. I'm genuinely interested in seeing what happens.). So, here's what I'd like you to do if you don't mind. For those of you who can check the PR of a site, log on to my site and then post the result on this thread. I'm wondering if some of you will see 4's and some will see 5's.

I would also mostly be interested in a reasonable answer if you have one.

Thanks.

 

That livepr link was cool! Thanks for that. After running it though, I'm seeing mostly 4 and a few 5s.

Somehow, a couple months ago, my PR dropped from a steady every day 5 to a 4 on many occasions. Now it looks like it's mostly 4.

Thanks again.
