I'll posit a theory, as I am also on the rollercoaster-o-random sales figures...
You are trying to predict the actions of humans! I've never met a psychiatrist I consider sane (probably haven't met one who considers me sane, but that's another story); this is because you can't possibly account for all of the stimuli which act upon a person and perceive their thought process.
Sure, it is an interesting exercise to try to fathom what could have made Monday's sales monstrous and Tuesday's sales tank. Interesting...but useless nonetheless...unless you have significantly changed your site. Meaning, if you didn't do anything different to your site, checkout process, available payment methods or any of the other major site components yet things are fluctuating drastically, sometimes but not all the time, then the issue probably isn't:
1) Your doing
2) Something you can (easily or with great effect) change
3) Worth worrying about because of 1 & 2

That being said, please provide me with the contact information for this Mr. Brian Williams so I may begin requesting wardrobe changes. We're sure pink is the most effective shirt color for sales increases? Should all weathermen wear pink? Or just Mr. Williams? Please advise.
