in the first mist born trilogy, it mentions that Rashek is a very powerful feruchemist, which has caused a lot of speculation on how feruchemical power is measured, as by its nature, a feruchemists power is determined by how full their metalminds are. my theory is that the relative power of a feruchemist is measured in how good they are at conserving power. in the end of TFE Sazed states that when a feruchemist taps large amounts from their metal minds that a certain amount of power is wasted. I think that the more powerful a feruchemist is the less power is wasted when tapping large amount of power. lets say X is the amount of strength required to make a given feruchemist twice as powerful as before, Y is the amount of strength required to make a given feruchemist four times as powerful as before, and Z is the amount of strength required to make a given feruchemist eight times as powerful as before. according to mathematics, 2X = Y and 2Y = Z. In reality, it would be 3X = Y and 5Y =Z. a weaker feruchemist would have 5X = Y while a very powerful feruchemist would have 2.00001X =Y.

I can't remember if this was covered in the books or not, but where did feruchamy come from? We know that the Terris people had it long before Allomancy and Hemalurgy became some what common in the Mistborn world, but I don't think we know anything else. The only thing that I can think of is that it is a magic system that combines the elements of Ruin and Preservation, although why it was only given to the Terris people is beyond me.
