Anyone heard of pixel transition ratio before?

Here's how PC Magazine test their cameras:

Quote:Pixel Transition

By analyzing other ISO target elements, we determined the pixel transition ratio, which defines image sharpness. We determined the number of gray, or transition, pixels between white and black elements, expressing this score as a percentage of the total number of pixels. The higher the percentage, the fuzzier the edges. Typically, 5 percent is the largest acceptable pixel transition ratio.

What do you think? Is it a bunch of baloney?

Jules, do you also read photography magazines for the computer reviews?

Hahaha, good point...

I think the pixel transition ration makes sense--it's like a measure of car acceleration--the distance from black to white along the transition zone (expressed as a %).
