Anyone who has managed a network knows that when you look at your MRTG/Cacti graphs at 5min, 10min ,15min intervals - all looks well. Start looking at 1sec intervals and you will see spikes that hit 100% of capacity - even on networks running at 25% average utilization.
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
