There is a balance between instantaneous reading and using cpu that your 
audio could be using. I am not sure if average or peak is being reported, 
but it is not suggested to run at 99% anyway. This is just a guide to 
decide on latency setting and plugin inclusion. The real measure of cpu 
use is xruns or not. This is just one more tool to help with no xruns.
