I think it's not about documentation, but about making bucks. People there probably struggle to keep their jobs and salaries... hence, they must shout at reunions about 1.37:1 or 1.33:1 or whatever being the right aspect ratio and Bob and other alumnis here being wrong, because if you / we get proven right, their whole pathetic careers might go down the toilets, along with their monthly earnings, which is all they care about. That's the only explanation: they pose themselves a specialists to people who have the checkbooks but can't tell otherwise, except when someone scream / shout at them in the room that others on the internet are unreliable. Damn the documentation, I saw the movie when I was seven! EDIT: This post incidentaly, begins page 166. The format must be 1.66!
