The page numbers in a epub are based on the number of files and the number of characters. To make it more fun, that number of characters is a compressed count. Depending on exactly what the compression ratio for a file is, the number of characters that make up a page can and does vary. One novella I am currently reading has 26 files making up it's text content which are 197,468 bytes of compressed data. Dividing the individual file sizes by 1024, rounding up to the next integer and then adding the numbers gives me 204 pages total. That number is consistent across any device that uses Adobe's page algorithm so page 92 is the same page no matter what you open it on -- handy for saying check the odd language used on a page

However, the page number has no relationship to the number of page turns I need to get to that page. With the Aura at it's smallest font size using my usual font and reading an epub, I get 2 page numbers in the right margin. At it's largest font setting, I need to flip 15 screens to get the next page number.

Hope this is of some use.

Regards,
David
