It simplifies the math too much, the nice level weighting is an essential 
part of the math and without it one can't really understand the problem 
I'm trying to solve. At http://lkml.org/lkml/2007/9/3/168 I provide an 
example of the math, which more acurately demonstrates the essential 
math.

bye, Roman
