I would assume it works in a similar vein to how the phases of the moon affect LUNAtics, which has been proven. Just because we cannot define the link, doesn't mean a correlation doesn't exist. Astrology has been around for years, and, while we cannot explain it, does seem to have some validity.
This is a pretty definite prediction. Next week should tell the tale. I'll be watching with interest. I have seen some pretty amazing predictions based on astrology come to pass.
