that average is for a large chunk of time, so it doesn't mean anything.
the point is that at any one given moment we aren't supposed to be able to
for example, if for 1% of the time I'm 2x the maximum, and for the rest of
the time I'm at 0, the average will be 2% of the maximum, even though
I exceeded the top
