[quote="zanash, post: 703705"]done it .... but the results were shouted down....even the 2db differences were considered as errors ... waste of time [/QUOTE] I believe that it was done for that blue light thing? If so you are correct, it was a waste of time doing what you were doing with the DEQ, it proved nothing. And as if a DEQ is a good enough tool for measuring potentially tiny differences. It's so coarse grained as to be useless.
