  results when reporting on lightly used regions.
  

Problem conclusion

• The Fast Path Region Occupancy report was updated for IMS V13
  to use the x'5904' record in determining Region Idle time.
  In the calculation for the various percentages the Elapsed
  time was based, not on the overall reporting elapsed time but
  elapsed time for each individual Region based on the
  transactions observed in that Region. In lightly used Regions
  this made for inconsistent results in the report, this
  inconsistency has been removed by using the report Elapsed
  time in the calculations for all Regions. In addition, some
  Not Active times were being incorrectly calculated, this is
  also addressed.
