Wayne, this is great stuff.  Can you clarify the methodology here though?  Are you simply dividing by the number of characters in the font set to find the mean?  Or are you using some subset?  If so, I wonder if that skews the results away from reality for typical content.  In other words, we should be computing a weighted average, where the weights represent probability of finding it in content.  Giving the difficulty in coming up with those weights, just looking also at the max, min, and standard deviation of width should suffice.

I did some calculations.
It is pretty clear that the distribution of font width is pretty narrow.
I have more data but here is the raw stuff without analysis.
