I think you are referring to this thread -

     As sampling rate approaches zero, so will the "spikyness" of the 
    graph--ultimately an interface is either sending a frame (*100*%) or
it's 
    not (0%). 

    -cjp


Utilisation doesn't "become 100%", instead measured utilisation will
either be 100% or 0% at each interval.
