 Final results are written to the standard output stream (so can be redirected to a file) as a single highly-detailed CSV record containing all the input settings and the output measurements (see below). There is additional control information that is written to the standard error stream and can be silenced in CLI. The control information also contains the CSV header, so it can be copied into a spreadsheet if needed.
 
-It is possible to invoke the tool in "Master apart" mode, where the master client is invoking a different activity than the workers, and at possibly a different (very likely, much slower) rate. In this mode, latency statsitics are computed based solely on the master's data, since the worker's activity is used only as background to stress the OpenWhisk deployment. So one experiment can have the master client invoke rules and another one can have the master client invoke actions, while in both experiments the worker clients perform the same background activity.

 **Clock skew**: OpenWhisk is a distributed system, which means that clock skew is expected between the client machine computing invocation timestamps and the controllers or invokers that generate the timestamps in the activation records. However, this tool assumes that clock skew is bound at few msec range, due to having all machines clocks synchronized, typically using NTP. At such a scale, clock skew is quite small compared to the measured time periods. Some of the time periods are measured using the same clock (see below) and are therefore oblivious to clock skew issues.
