It's been confirmed that all the "scaleable" rewards (cash, Orux OR faction) are all scaled in the same way depending on how "popular" the missions are. I think a 'rule of thumb' of 1 faction point per 2 orum was estimated - this would fit reasonably well with 4x50 orux missions to hit indifferent and 8x50 for amiable. (Going by some very old data, Apprehensive = -100, Indiff = 0, Amiable = +100, Kindly = +500, Warmly = +750, Ally = +1100)
EDIT: The relationship between those and the 'single' tasks which don't give Orux but cash instead isn't well defined, but it's ESTIMATED that 10 of those = 1 group mission. If 1 grp mission = 50 orux = 25 faction, 1/10 of that is 2.5 -- which would not fit neatly. I suspect it's more like 1/5th, which, with most of the single would translate to 1/25th of the PP reward since most of the quest-type tasks have a 75pp reward.
