Optimality is measured by a series of questions “At what time of day do you feel at your best?” asked for each hour of the day and scored: definitely yes = 100; yes = 75; mixed, undecided = 50; no = 25; and definitely no = 0. Personally optimal times are highlighted. US university students.
Adjustment so that each case has the same maximum and so weighs equally in the optimality calculations. The ajustment for each score is: NewScore = OriginalScore/OriginalMaximum. For case #12 that comes to: NewScore = OriginalScore/75. Most other adjusted cases are the same although a few = OriginalScore/50. The decimal point is adjusted to run from 0 to 100 for this table (so it is comparable with raw scores).
