Weird count in permalink

Heya all,

I’m having a weird thing going on here, or maybe, I just think this is weird, let’s put it that way.

When I post a blog, it gets a number ID, but when I post a new post after that, it gets a much higer value.

Example:
I post on the 4th of may a post, p=1132
The next post, the 7th of may, p=1134
BUT I only have 353 posts on my entire weblog.

Who knows something about this, is it just normal or what?

I just think it’s weird…
