+## Specify multiples of clock resolution to run benchmarks for
+<pre>--benchmark-resolution-multiple &lt;multiplier&gt;</pre>
+
+When running benchmarks the clock resolution is estimated. Benchmarks are then run for exponentially increasing
+numbers of iterations until some multiple of the estimated resolution is exceed. By default that multiple is 100, but 
+it can be overriden here.
