I know what my eyes tell me and I haven't seen any deterioration of the view at the edges on the Wind River Olympics, which have followed the Wind River P1. We are talking about $45 for a view in the Wind River Mesas comparable to the Wind River Olympic. Not 3 times the price of the Trashco EXP.
http://betterviewdesired.com/10-02/leupold.htmlThe matrix you show is obviously highly subjective, compares apple and oranges, and is obviously worthless. It rates the Nikon Venturer LX 8x32mm the same as the Tasco EXP. There is no comparison between them and they cannot objectively be given the same rating.
The only way to compare binoculars is with your own eyes, properly focused and stacked so you can go quickly between pairs resolving difficult targets under varying conditions, certainly not from a chart put together by many different eyes, viewing too many different kinds of binoculars and over too long of a period.
I believe your are right, the operative word is CHEAPER when talking about the Tasco EXP.
cheaper:
Of or considered of small value
Of poor quality; inferior
Worthy of no respect
Relatively low in cost; inexpensive or comparatively inexpensive
