Could it have been due to these small updates within that time period?

Pr juice is gained/lost every time a spider visits your site from a backlink and for google server update pr regularly. It's a different thing if they not update it in toolbar.

An Interesting Thought
A whole industry exists in selling PR, don't think Google hasn't noticed this and doesn't view it as a big problem.
So much BS talked about on this thread, time to clear a few things up:
1. This website explains how / when the toolbar PR is updated (The PR you know About) http://www.hobo-web.co.uk/google-pr-update/
2. As you'll begin to tell, no one knows when / if it'll be updated again.
3. Someone mentioned PA / DA - These are not Google measurements, are easily gamed and shouldn't carry as much weight as they do IMHO.
4. If you're buying a domain it takes a few minutes to do some elementary back-link research. Don't rely on automated crap to do your due diligence, the best tool you have is ahrefs / majestic, google and that piece of grey between your ears.
Well, all I am going by is what you are saying. There happened to be an update around the time your PR got "hit". You must not have been updating your content or some of your backlinks got deleted or deindexed.
Normally Google update PR in every 5-6 months.actually no one knows when google will update PR .
Who cares about why pr dropped ? the thing i care is that their pr was updated.

You are right there. DA/PA are not good because they can be easily manipulated or faked. But, I think if the requirements for the PA/DA were increased or modified, it could be better. Much better.
I use Ahrefs primarily for link research and for getting an idea of how much authority a site has. Majestic SEO is my secondary link research tool.
From 2013 onwards Google change the PR update process. Before that "PR has been updated 3 months once". But now, its fully depend on Google. According to Google humming bird algorithm there are "200 more ingredients"
I have found that last time it updated 2-3 months ago. I am not sure but for the next update you may have to wait for 1-2 months.
Normally Google update PR in every 5-6 months.
Where is everyone getting this 2-3 months ago? The last PR update was the beginning of December 2013
