I am guessing $ volume. I also wonder if it is some kind of decaying rank (sales today count more than yesterday which counts more than 2 weeks ago).

I don't know if this helps, but our recent book sold about 4000 copies in 9 months--that would be about 15/day in total, not just Amazon, and it's typically ranked around 5000 on Amazon. My point is that technical books such as mine sell proportionally more on Amazon, while Stephen King etc sell more in stores. I'm not sure where your book falls in this spectrum. Hi, Seth.
