Re: Are 2 pixels per line-pair enough?

I finally found the image I was looking for, from here:

If you look at this image (of which I've taken a screenshot and re-posted)

you see that the red line identifies one letter which is quite clear, while the surrounding ones on the same line are progressively less so, and no E is clearly visible on a smaller line.

Now, I'd expect that the "all characters are visible" line would need to be 1.5 times as large as the "one character is visible" line - but that does not appear to be the case here.
