Tell me more. What is meant by that?
What that meant was the inconsistency of it all. . .either the machine is 100% accurate or it is not.
If the machine is not 100% accurate then not a single operator can claim HE is 100% accurate.
It is a logical inconsistency to accept the premise that every operator can say THEY are always accurate when these same operators state that all other poly operators are not 100% accurate.
Excellent report on the poly and how it is unproven and wrong most of the time: http://www.nap.edu/openbook.php?isbn=0309084369
National Academies Press published it.
