Is Savantism Additive or Multiplicative?

[JustQuestin2004 he/him]

A thought just occurred to me, there are Allomancers of differing potency, like with Vin and Elend. They have an innate difference in terms of sheer power without Savantism. Then there is the boost one can gain from Savantism itself.

My question is thus, do you think a Lerasium Mistborn and Diluted Mistborn gain the same level of boost from Savantism or would the Lerasium Mistborn be a better Savant?

I think that it might be multiplicative, because there are two very different levels of Investiture flowing through them, which would cause more warping of the soul. 

Or if we go from another angle, a Misting having their powers doubled or more by additional spikes granting the same power they already have, like Steel Inquisitors with Bronze Spikes to double their Seeking. Do you think they'd have the same level of boost from becoming Savants as regular Seekers, or are they getting a little more from their Bronze Allomancy being stronger?

I am inclined to believe hemalurgy is additive, because you're adding the allomantic/feruchemical potential of the spike donor to the recipient's spiritweb, but savantism is multiplicative, since stronger Allomancers are drawing larger quantities of investiture from Preservation, so more investiture is affecting their body than a weaker Allomancer burning the same amount of metal, the rational mind will see this.

I know Hemalurgy is additive, I was referring to becoming a Savant when having a double-boosted power from Hemalurgy. As a second comparision to Lerasium Allomancers in terms of more potent Allomancers and how the extra power might effect their boost from Savantism. 

But yeah, that's kind of what I was thinking. More power per second will cause greater warping of the soul.
