Very nice page. The only suggestion would be to reduce the fraction 126 / 512.
In mathematics, you don't understand things. You just get used to them.
I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.
Looks very good to me.
