I'd rather not listen to anyone. Just put up documented data describing ones methods or procedures, the products compared, and the results.
I see statements here like 5 to 1 failure rates. How many of each were compared? If there were 500 X's and 100 Y's with respective failures of 100 and 20, then we have similar rates of 20%.
Show us some data please. The videos exhibiting 1 Burris, Leupold, Tasco, etc that are not even remotely similar products (i.e a 12X vs a 6X vs a 20X) does not a trial make.
