The statistics offered for epub, with a little trick, are: reading percentage, Hours of reading, current chapter % (may be not really working for epub, always zero for me) media Minuit for reading session, media page for Minuit. And for all books: % of finshed books and number of read books. Nothing for pdf.
You can add a line in a file to have statistics for epub (not when reading but pressing for a while on My books) The file is:
Kobo eReader.conf in the hidden directory
.kobo/Kobo/ of Your Kobo device.
In the following section (if there isn't create it) add a line:
[FeatureSettings]
BookSpecificStats=true
I use Linux so I haven't got the problem but if You use Windows may be better not to use Notepad or Wordpad, but something more similar in end of line to Unix, like Notepad++.
for more information see, for example, that thread where I apprehended this little trick:
