Benedict created CASSANDRA-6921:
-----------------------------------

             Summary: Remove "adjusted op rate" from cassandra-stress stats logging
                 Key: CASSANDRA-6921
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6921
             Project: Cassandra
          Issue Type: Improvement
          Components: Tools
            Reporter: Benedict
            Assignee: Benedict
            Priority: Trivial
             Fix For: 2.1 beta2
         Attachments: 6921.txt

The adjusted op rate is probably confusing to users, since I don't ever tell them what it
means. It shouldn't be used to interpret any performance data, and is only really useful for
calculating the _standard error of the mean_ which _is_ reported to the user, and is also
used to calculate the point at which the op rate has stabilised to within the error threshold
in the "intelligent" mode.

As such, I think it should be removed from the output.
