I have just noticed there is a new "pages" number in the book info and I have seen from
other posts that it is used to calculate the width of the covers in bookshelf view (nice

I like that view and I wondered how it was done).
I already have the Count Pages PlugIn installed and I send the page count to my kobo as a subtitle, because I hate the kepub system of "screen count" which changes every time you change font size or font or literally anything.
So now I have 2 page count numbers and they are not the same.
Question 1. how is the new page count calculated? Presumably based on x characters = 1 page?
Question 2. where is the new page count data stored and can it be added in a column, specifically the column I currently use for the plugin ? If it can't, I will just modify the plugin to calculate the same way, if it is based on character count, so that the two agree.
I would rather have only one page count number (even if it's displayed twice) and I am not bothered which one it is but having 2 different ones is triggering my OCD.
