It really depends on the period they use to calculate it. My book was very briefly the #1 programming book on Amazon[1], which is, I think, a decent-sized category. I don't know the exact numbers, but I probably sold a few hundred copies that day. But, more importantly, I think I had a narrow spike of a lot of sales in a couple of hours right when the book first launched.

It depends. They're calculated hourly. Right place right time...could be just a couple dozen. Books sell less copies than people think.

That's interesting, do you have a sense for what the incremental sales were from having the #1 designation?
