"top" shows different CPU usage than "ps faux"

I just noticed that "top" shows a CPU usage percentage markedly
different than "ps faux" for example.
In this case, a java process running at 433% in "ps faux" is shown as
runnging at 661.4% in "top"
Both programs get their data from the /proc filesystem I imagine, so
there could be a summation bug in either of them.
Or is there some rational explanation?
