My nybble's worth: 

  95th percentile is usually based on a 5 minute average, and when you
have a lot of upstream bandwidth you can move a lot of data quickly and 
it barely shows in a graph/monitoring system doing 'mrtg' style 5 minute
samples.

  It's better than nothing, and identifies 'hogs' quickly.

  Because of the large amount of 'business hours' users we have, I've
made some special deals to some 'off-hour' bandwidth hogs because of the
available and unused  bandwidth during those hours. --Mike--
