I noticed that when your strength stat increase, so does your carrying capacity (obviously). But what I was wondering, is why the difference in weight limit that you gain increase as you strength gets higher? For example, you seem to gain greater carrying capacity going from 20 to 30 str than from 10 to 20 str. I don't know if the increase signifies a geometric or exponential trend or what, I'm just wondering why it isn't arithmetic or linear.
And does this apply to other stats, or aspects of other stats also? Do you get greater benefits from having your stat grow (see previous example) at a higher level for Willpower, Dexterity, etc?
Well, just something that had been bugging me, if anyone has an answer for it I would appreciate it.
