Oops... default file permissions don't let anyone but the owner read a file. When you run the analysis, it can't read the newer log files that got created under that restriction. I just added a line to my main stat generator that will change the permissions on the log files each night (as new ones get generated) so it should work better now. Keep in mind, each DAY of uncompressed logs takes about 150MB, so I tend to compress them and store them at the end of each month. That means when you generate statistics, it'll usually start at the first day of the current month... sometimes I'm late and you'll see the previous month as well though. Either way though, you should still get results up until at least the day prior to when you run it. Also note that the server runs on the UTC timezone, so times/hours in the stats are shifted about 1/4 day for north american users.
