First, try to refrain from answering 6 month old posts.

Second, if you do answer 6 month old threads make sure you are correct.

The following excerpt is from Adobe's EPUB Best Practices found on Adobe Developer Connection's Digital Publishing Technology Center page.

Quote:
Synthetic page names
When page map is not available in the document, Adobe Digital Editions will synthesize a page-map based on the document content. The approach used is the following:
  • Determine a compressed byte length of each resource which is referenced in the spine, subtracting any known encryption overhead (IV size)
  • Assume that there is a page for each 1024 bytes in each resource, rounding up to the nearest whole number of pages for each resource
  • To map page breaks into a resource, use the number of pages for the resource as determined in step 2, count the number of Unicode characters in the resource; distribute synthetic page breaks in the resource evenly between the characters by dividing the number of characters by the number of pages; if the number of characters don’t divide evenly among the pages, round the number of characters per page up and let the last “page” contain less characters than the rest.
Your 505 uses ADE's ePub renderer and in the vast majority books the page numbers are generated based on the number of bytes in the book. I have yet to purchase a epub that used a template.xpgt file to designate actual page numbers.

The page numbers in standard english 505s are in the right hand margin. This is a creation of the version of ADE renderer used on your reader. There are newer Sony devices that have removed the page number from ADE renderer.
