Conclusions
When agent is Idle and ready for a new mission, and you are offline, Fatigue goes down at approximately 1% per 5.75 minutes.
Guesses:
(Normal Fatigue rate)
Tier 1 - 1 hour mission - Successful = 10% Fatigue
Tier 2 - 1 hour mission - Successful = 15% Fatigue
Tier 3 - 1 hour mission - Successful = 15% Fatigue
Tier 2 - 8 hour mission - Successful = 15% Fatigue
(Reduced Fatigue rate)
Tier 1 - 15 min mission - Successful = 7% Fatigue
Tier 1 - 1 hour mission - Successful = 7% Fatigue
Tier 1 - 15 min mission - Outstanding = 4% Fatigue
Tier 2 - 4 hour mission - Successful = 11% Fatigue
Tier 2 - 8 hour Mission - Successful ~= 11% Fatigue
Tier 4 - 8 hour Mission - Successful ~= 11% Fatigue
Disclaimers
There may have been slight delays of a couple minutes after turning in a mission and starting the next on a few occasions and that may be the cause of some slight variability in my test cases above.
When testing Fatigue decay, the time between each recording is not exact, and the Fatigue is displayed as an integer while internally it probably keeps a few decimal places, so some variances are expected in the data.
Fun tidbit:
/reloadui updated the Fatigue % for me
Edit:
I’ve been told by someone else on these forums that Fatigue was going down by about 1% per 8-10 minutes for them while online the whole time. So there may be a difference if you are online vs offline.
