 Usage: ${programName} [OPTIONS] [ACTION]
 Benchmark pv transfers - take measurements of transfer rate and CPU usage
 when calling pv in various different ways, and analyse results from multiple
-benchmark runs to show how each measurement changes over time.
+benchmark runs to show how each measurement changes between runs or versions.
 
 Actions:
