i recently changed the format of the permalinks in a couple of word press blogs to one that is more search engine (and human ;-) ) friendly than the WP default. I noticed after doing this that WassUp seems to record one and the same page look up multiple times as a result. This of course makes the page per visit number totally wrong.
Here you have a typical list entry

The blog is not in English, but I guess it is easy to see that the look up is recorded multiple times.
