I am surprised that you can say something like this without doubting 
your judgement, or calling your experience into question. Don't you 
think there is a world where redundant data can be a problem in one 
corner of the universe (your corner) and there are other corners 
(including Math) where it is not? Neil Soiffer and the folks at Design 
Science have a lot of data that supports their claims, and it seems to 
me bad engineering (possibly leading to flawed designs) to just dismiss 
this at the stroke of the keyboard. What are you expecting the 
discussion to become here, a children's shouting match with "but I am 
right" ... "no I"...?
