Wouldn't many rounds of running with different data sets (to minimize cache
hits) and timing with time also serve the same purpose? Does time introduce
some unavoidable minimum margin of error for short runs that will get
multiplied by the number of times and drown the actual measurement? If time
only introduces fluctuations they will cancel each other out in many runs
but if there's an unavoidable minimum error then multiple runs won't help.
