Your maths are correct. I started selling the book in January 2012. However, I think I could have achieved this number of sales much faster if I dedicated more time to marketing (e.g. if I published the same number of posts in half the time).
Pricing is something I learned about from 30x500 as well. I looked at the anchors my potential buyers might have (C++ books are often around $50).
I looked at what else they buy and at what price (courses, software etc.).
I also considered the value of the book to them. E.g. for a C++ contractor, the book would pay off very quickly because of the time savings it provides.
