Question: Total number of Functions in Maple

This is branched from Maple 16.01

I don't know the reason for the break.  In trying to replicate the graph shown for Mathematica for Maple I am finding it difficult to locate the number of mathematical functions for various versions of Maple. 

The only reference I find is that Maple 16 contains over 5000 mathematical functions, many more than Mathematica 8, but they are programmed different so I can't compare that.  However trying to compare it to previous versions would require some input from someone at maplesoft to help. 

Another interesting note is that Maple 15 and Maple 16 both contain 270 new mathematical functions where I find that referenced in various advertisements ( I think someone just forgot to take it out for the new advertising)

So the question is what is the total number of functions for various maple versions?
