lol do you actually live in LA to witness the towers going up everywhere over the last 10-15 years? also, 3 orders of magnitude is 100% -> 10% -> 1% -> .1% of reported numbers.
The other way around, to me this means that the total floor space is the size of a 66 meter square, which is ridiculously small. I think it must have been at least 1000X times that
I assume the numbers are normalised for the number of buildings, otherwise the comparison would be meaningless.
