If the ROI score is under 60, then by social convention it is in the “completely normal” range within two standard deviations.
If the ROI score is over 60, then we may judge to investigate the complaint further.
This is apart from the player’s own ROI score, which may be “completely normal”---or not, leading into the next case.
It compares against pinpoint expectations, rather than against broad averages as in the screening test.
This results in a lower score on the z-scale, often landing in the completely normal range when the screening score was above 65.
