If the minimal pause is at least a half second, there is enough variability to notice changes as the load on the system is increased or decreased. There should be no terminal IOs between the T0 start point and the T1 stop point.
REF: For more information on RT measure, please refer to the
Resource Usage Monitor (RUM) documentation, located on the VDL at the

Output variable (start time).
NOTE: On Caché systems, it only records to the nearest second.
