It seems to improve legibility. I'm not so sure it improve readability.
Readability is largely influenced by the x-height (height of lowercase letter), because your brain is trying to discern the "shape" of a word - which allows you to read faster. Hence why ALL CAPS is difficult to read because the word shape is the same.
Atkinson appears to have a high x-height, which reduces readability.
Agreed.
