what all this tells me:

* I could increase the usage of my website by a factor of 15.7 before I hit the bandwidth threshold for my account at Pair
* assuming that revenue increased in linear proportion, and that I could improve the conversion rate, I could increase my Associates & Associates-driven revenue into the several hundreds of dollars per month
* increasing usage by x 15 would be hard work, there are other things I could do that would increase revenue more (i.e. publish more or better books)

My website has always been a bit of a mess because I use it as a combined blog and bookstore. It would be better to have a single purpose store. Right now the website is under construction as I experiment with new Amazon Associates widgets.
