I wish I could beat this into some peoples brains.  They expect models 
to be perfect all the time.
 
I have been told that if the model isn't working, then we have to look 
at different tools to model it better.  I think that is part of the 
issue in this case.  Simulation says one thing, real world says 
something else.  In our case, the real world is the problem and we do 
need to be closer to the simulation.  I am thinking that the real world 
is related to the way that the circuit was constructed as a big part to 
the issues.
