One definition of "optimum allocation" is providing the same usability
for operators of every mode. In order to accomplish this, one needs to
know the number of people who wish to use each mode. It's not possible
to directly and accurately obtain this number, but perhaps counting the
number of QSOs in progress might approximate it.

In the absence of any data, I'm not going to speculate about whether 40%
is a reasonable number. Have there been any attempts at measuring
utilization in an objective way?

The USA band restrictions serve a very usefull purpose for the rest of
the world. It gives us a chance of finding a frequency that is not
full of american chatter. If the band is open the USA general section
is almost invariably solid with high power QRM.
