What numbers are you talking about?
I get "Location" numbers, which every book has -- those are based on an internal algorithm.
Only if you have an APNX do you get "pages".
Unless something has changed without me hearing about it, on the newer hardware (I have a Kindle Touch).
If the device is showing "pages" instead of "locations", everything I know so far would lead me to believe there is still an APNX somewhere....
Although personally, I find Time Left To Read the most use. Obviously, not when I need to cite something.
