Mathematically speaking is true, but maybe is not true in real world.
I have seen a lot of times people not using the last level of zoom
(how many times you have to see a whole road or even more then one
road? ) therefore the traffic will not be 4 times more. Also, even
considering '4 times more' as true, we have to consider that is only 4
times more the traffic generated by the zoom level 18, not the whole
OSM traffic.
I think it would very important to know the actual saturation of
processors, hd and traffic to be able to give a though point of view
over adding a new zoom level.

my two cents,
Fabio
