Experiments are an important way to sanity check ideas and simulation results.  
There are lots of ways to put bad assumptions into a simulation model and get 
results that aren't real.  But the flip side is that all experiments are 
limited in their ability to isolate the controlled variable.  Even assuming 
that we have not made any mistakes in our set-up or measurements we still 
always need to be wary about generalizing the result of any given experiment or 
experiments.  

Best Regards,

Steve

  All of the things proposed don't seem to have any basis.  I, on the other 
hand, have built test boards to find out.  My findings are available in my 
classes and do not show such vias have any value.
