In any experiment there will ALWAYS be experimental error. These errors can be large or small, random or systematic or both. When comparing experimental results, the most important measure is the experimental error. Thus proper way to report the results is to state "The M3 accelerated to 60mph in 4.8s +/- 0.5s" for example. Notice the error is truncated to the proper significant digits.
This is important to keep in mind when comparing lap times, acceleration, etc. results. Although we don't know the experimental error, for the above quoted lap times, it is safe to day that they are EXPERIMENTALLY EQUAL.
