Showing Number of Results

Sometimes, when I run a search the number of results ("Showing 1-10 of 12") is not shown.  This seems to happen only when there are 5 or fewer results.  Can anyone confirm if this is the case.  If it is, I am curious (a) why you wouldn't show the number of results no matter how many there are and (b) whether this is configurable.

I've got the oposite request, I would like to hide it whatever the number (i have a tide display that shows next 2 days tides) and it's annoying having showing 1 of 8 at the top continually - whereas on another page it only show the next 4 tides, and it doens't.
