1. Yes. That company is relevant. They provide data based on rigorous testing. That data is relevant. Sorry. The sensor in your whatever brand camera does or doesn't measure up with Sony sensors in bit-depth, dynamic range, or low-light performance according to lab testing. Here's how the current crop of sensors rank based on these key metrics. This is how much each costs. Where on that "linear programming" grid is the IQ optimal and the cost minimal? There is only one point where those lines intersect. Down the road that may change. But this is where it is now...
2. Yes. Your choice is wrong because it was likely an emotion-based not reason-based decision. I provided the reason based path, which is a fairly narrow one, right down the line from body to lenses provided your goal is to maximize IQ and minimize cost.
I think no one is questioning the data relevancy, rather the relevancy of that data (and the company per se) related to how it makes your photography better.
