Yes, but are any controls capable ensuring lack of "variations between 
PCR runs"? I believe it has been well documented that a +/- variation
can be obtained between individual block positions in the original 
Perkin-Elmer machine.

Personally, I find identical PCR reactions are never that. Seeing 
the lack of PCR products described as any kind of  "result" I find very 
hard to swallow.
