Google Directory

Page rank in directory is different

[prejudice]

Hello,

Just a quick question about the page rank in the google directory.

I recently submitted the my site into dmoz about 2 months ago and got in fairly quickly. Just noticed my first hit to the site from Google directory today.

So I checked up on the link and it is showing number 1 in the list (listed in order of highest pagerank first) with a pr6.

What I don't understand is my site is only a pr4. I have recently increased my link back count within google four fold, so my question is this... Does this pr6 indicate what might be ahead or is this just purely google being messed up?

Thanks
