The number of pages shown depends on how many posts are made.. in my case I choose to display "New posts since last visit" so I may get as few as 2 or 3 if it's only been a few hours (my last pass of the night) or as many as 15 if it's been a long time (day and a half) this last happens when I am on the road, do a morning run, Drive all day, Eat, sleep, eat, drive and then do another run the next Evening.
