I picked up on that as well. Wikipedia seems to agree with us: http://en.wikipedia.org/wiki/Lifetime_value

I agree with their points, but overall the article is just a little bit "off". Maybe it's the bit about the integral. If you had a customer pay you $1 every month, and they on average stayed for one month, your LTV is $1, not the integral of 1*x (1/2).
