If I may, I don't think we all agree on the same definition of low, mid and high level. Hence, we don't have any formal, unambiguous, accepted metrics. So we cannot classify anything.

I have the feeling that most of us are saying the same things. The point is that someone says C is 10 meters high, others claim it is 32.8 feets...

Not exactly, I would say that more people are saying C is "tall" because it's not as short as the height of a pebble off the ground, as a way of being optimistic about C, even if there are things taller than it. (i.e. it doesn't classify as "short" because too many people own a measuring tape, and have an exact idea of a certain margin.)
