Most efficient use of Renown?

Easiest way to adjust fatigue (outside of using SH3Cmdr) is to edit the SH3 Basic.cfg file (in Cfg folder). Look for the [FATIGUE_COEF] block. Setting all positive values in this block to 0 will eliminate fatigue altogether. That is:

[FATIGUE_COEF]
;comp0 tower
RegularFactor00=0
SpecificFactor00=0
BadWeather0=0

;comp1 sonar/radio
RegularFactor10=0
RegularFactor11=0
SpecificFactor10=0
SpecificFactor11=0
BadWeather1=0

;comp2 command room
RegularFactor20=0
RegularFactor21=0
SpecificFactor20=0
SpecificFactor21=0
BadWeather2=0

;comp3 diesel
RegularFactor30=0
RegularFactor31=0
SpecificFactor30=0
SpecificFactor31=0
BadWeather3=0

;comp4 electric
RegularFactor40=0
RegularFactor41=0
SpecificFactor40=0
SpecificFactor41=0
BadWeather4=0

;comp5 bow torp
RegularFactor50=0
RegularFactor51=0
SpecificFactor50=0
SpecificFactor51=0
BadWeather5=0

;comp6 bow rest
SpecificFactor60=-0.1
SpecificFactor61=-0.1

;comp7 stern rest
SpecificFactor70=-0.1
SpecificFactor71=-0.1

;comp8 stern torp
RegularFactor80=0
RegularFactor81=0
SpecificFactor80=0
SpecificFactor81=0
BadWeather8=0

;comp9 deckgun
RegularFactor90=0
SpecificFactor90=0
BadWeather9=0

;comp10 flak
RegularFactor100=0
SpecificFactor100=0
BadWeather10=0

;comp 11 repair station
RegularFactor110=0
RegularFactor111=0
SpecificFactor110=0
SpecificFactor111=0
BadWeather11=0

But I would first recommend that you try some of the alternative fatigue models that have been developed. There's a few around! Some are just simple variations of the standard fatigue model whilst others are whole new methodologies.
