One of professors explained compatability by saying put someones big toe
centered under a flat 2x4 supported with a brick under each end, and hit the
2x4 over the toe with a sledge hammer.  Times 10 toes for the standard
method.

But Jordan, Scott is simply suggesting the "Simplified Version" be applied to
the code writers!

I think we may need a tiered system like seismic and wind, where there is a
simplified version for lower load areas and/or simple structures. It's good
to have ready access to the exact formulas for use in practice - sometimes
you just need an exact answer. But for smaller, straight forward projects
they just add a large burden to the engineering fee.  
And I don't agree with you on waterboarding. While I'm certain that it
probably would be defined a torture by many, I feel - personally - that with
the tremendous knowledge and creativity of the practicing engineers in this
country we can certainly devise far more painful, traumatic, and emotionally
scarring experiences for code writers. :-)
