5. RLS - Average Release: The average time taken, after the REST
prompt to reach 37.5% of the previous third second of work
or as in item 4 above, the second second if only 2 seconds of
work has been selected. As in the case of Onset, if any Release
of the trials is more than 2 seconds then it (or they) will be
rejected and the display will indicate the average of only those
which were 2 seconds or less but a dash (-) before the number
displayed will indicate this rejection.
6. If all the Releases were more than 2 seconds then the display
will read AB2.
