Reduced Duration

Reduced Duration is the opposite of Extended Duration, since that is also called Increased Duration, RD could also be called Decreased Duration.
==Applying to durations introduced by limitations==
An ability like Altered Time Rate does not normally have a duration. However it is given a 1/60 duration in the advantage Celerity in Pyramid 4/3.
This appears to apply to the 60 seconds of operation introduced by Requires (Attribute) Roll which it is also limited by.
This is the only known example, it's probably not intended to work this way using Maximum Duration.
==Breakdown==
http://www.sjgames.com/gurps/faq/FAQ4-5.html#SS5.1.4
*-10% for 1/3 duration
*-15% for 1/6 duration
*-20% for 1/10 duration
*-25% for 1/20 duration
*-30% for 1/30 duration
*-35% for 1/60 duration
*-40% for 1/100 duration

:Maybe -10% for 1/3 duration, -15% for 1/6 duration, -20% for 1/10 duration, -25% for 1/20 duration, -30% for 1/30 duration, -35% for 1/60 duration, -40% for 1/100 duration, etc. About 1/3 off for going from minutes to seconds seems quite fair.
==Variation==
In GURPS Power-Ups 4 pg 4 under "Aura of Power" the "Reduced Duration, 1/60, Only after the target leaves the area" limitation is valued as -30% instead of the usual -35% for 1/60.
This indicates that "Only after target leaves the area" is either a +5% enhancement, or that this reduces the value of the RD limitation by 1/7

:I must say that I regret not putting it as two modifiers. Bruno is right, it's +5% for the quality of life enhancement that once someone is blessed by the aura, you don't roll again, and the original duration will apply once they leave it.

:this value was determined in a long, three-way discussion between him, Kromm, and myself
:Aura + Area Effect means that the ability keeps firing off every second. That means that every person in the area has to make a HT roll every second until affected.
:what Toni wanted to do was to effectively remove that "then a second off", approximately doubling the amount of net time that the subjects were affected. As that was similar to doubling the duration, it was ruled that the net value should be equal to that of Reduced Duration 1/30 (instead of 1/60), a +5% difference.
