Theorem Infection Giving Only ~Half Its Bonus

[(XBOX)TheWayOfWisdom]

Theorem Infection only gives a bonus of approximately 13% per stack.

I used Nyx's Absorb to measure damage values with a lvl 6 specter using an Exergis.
With no buffs: Specter does 2034 damage. That matches the expected value of 1620 x [1 + 0.015 x (6 - 1)^1.55] x (17/16) = 2034

The 17/16 comes from Quantization. The TL;DR of that for now is that elemental damage buffs (like Theorem Infection) scale off the damage before being multiplied by that value (So Exergis has a base damage of 1914 here). Another consequence is that our max buff from Theorem Infection should be 58/16 = 362.5% instead of 24% x 15 = 360%.

So with 15x Theorem Infection stacks I'd expect my specter to do 1620 x [1 + 0.015 x (6 - 1)^1.55] x (17/16 + 58/16)  = 8974 damage.

However, the Specter only does 5743 damage. (5743 - 2034)/1914 = 193.75% bonus from Theorem Infection.
So the value per stack is approximately 13%, not 24%.
