Thank you Jackie. I think I've found the details elsewhere on this site:

Does anyone have experience of doing this on the Kobo Aura One and what effect it has on readability?
I can't help wondering why the default would be set for frequent (1-6) page refreshes if it works perfectly well without them.
Maybe others don't find it as irritating as I do - or as I think I would, as I can't actually test run it.
