I'm all for tests and scores, but every test and scoring system has weaknesses / strengths, which need to be taken into account when looking at the results.

The studio scene is a good way to judge sensor performance, which is probably it's strongest aspect in my opinion.

Sharpness (detail) is a bit more difficult to judge because there might be tiny focusing errors (as have been seen before), or issues with the lens used, as not all cameras use the same lens. I believe the sensor's impact on detail is easy enough to predict based on specs alone, i.e. more pixels = more detail, no AA = more apparent sharpness.

Colour is a strange one because the studio scene will fade over time, and at the end of the day it's not a typical subject where pleasing colour can easily be recognised. I prefer the sample galleries for judging colour instead.

Agree, snapping an image of a piece of paper is completely different to translucent skin tones. and believe me if you get the lighting wrong there no going back in post. You can clearly see the poor quality of the head shots just by looking at the hot spots.
