P3D PS on "why the 1/30 rule does not work"

["Dr. George A. Themelis" <DrT-3d@xxxxxxxxxxxxxxxxxxxxxxxxxxx>]

I am sorry if I sound too harsh on my good friend Tom.   He has
done an excellent job in presenting complicated formulas for
us to use right away.

My only reservation is on the nature of these formulas. I think
they predict a limit, not an optimal situation.  Still, it is
good to know the limits. The 1/30 rule appears to be a conservative
approach.  It works but tells you very little about why it works 
and how far off the limit it is.
