Some benchmarks include their own runner which provides an overall average and a standard deviation. This enables extraction of that value similar to the other measurements. These benchmarks should only be run once. If a benchmarks specifies multiple runs and provides a standard deviation, a warning will be issued that makes the build fail on the buildbot side.
