It's a big 'ol AdSense world. I had a better-than-average Fri-Sun by about 15%. So many variables involved, it's just impossible to know the "why" and "wherefore" most of the time, especially if you haven't made changes or seen traffic fluctuations to pin it on. Hang in there and keep adding useful content and getting good, on-topic links to your site(s).
