I think that this is because the Linux graph is so unpredictable - it
is all over the place in the graphs collected by Andy, and which
someone else agreed was the case under Linux - it has more spikes than
my son's hair. Anyway, because it's so unpredictable, it can be used
to prove that Linux performs better than any other operating system at
any point in the graph (whilst at the same time handwaving away that
it's performing worse).
