FAID Quantum uses the FAID Score

There is no unit or absolute measure of fatigue.  The FAID Score takes into account:

  • Duration of work & breaks
  • Time of day of work & breaks
  • Work history from preceding 7 days
  • Biological limits on recovery sleep

and produces a FAID Score.

To assist the interpretation of FAID Scores consider the following benchmarks:

  • Working Monday to Friday: 9am to 5pm produces a Peak FAID Score of 40
  • Working Monday to Friday: 11pm to 7am produces a Peak FAID Score of nearly 95
Peak FAID Scores for various Day and Night Shifts
