Not that I disagree with your primary point, it is worth noting that there 
is some basis for hovering about 7, for an *overall* model.
It's that memory limit thing (7, plus or minus 2.)  The plus or minus is 
statistical, so if you want to make sure that people really have no trouble 
grokking the total set, 5 is a better choice.
