Base it on the data. Look at the overlaps and differences in their behaviors, wants, goals and needs. When you find a significant difference in behavior that warrants a unique design case, then and only then do you create another persona. There's no magic number of too many or too few. There's only what the data tells you. Coming in and saying "there should never be more than five" without being able to back it up with data will get you into trouble and is frankly inaccurate, which equates to bad design. Cheers!
