Novus weapon upgrade system findings

[Donjo]

do i live in a different world or why was i tought that 44 + 31 equals 75...?

Let me do the Math for you. Let's take two i110 weapons that currently have Determination.

The Glanzfaust: 44 Accuracy and 22 Determination. 44 + 22 = 66.
The Book of Spades: 31 Crit Rate and 31 Determination. 31 + 31 = 62.

66? 62? What? Don't we have 75 points to meld? Let's look at a couple of other weapons.

The Laevateinn: 44 Accuracy and 31 Spell Speed. 44 + 31 = 75.
The Rosenbogen: 31 Crit Rate and 44 Skill Speed. 31 + 44 = 75.

Ah, that's better. So, why do these weapons without Determination add up to 75 and the weapons with Determination add up to something lower? Because Determination has a higher weight than other stats. i110 weapons have a cap of 75 "points" of secondary stats. Crit Rate, Accuracy, and Spell/Skill Speed have the same weight. They each cost one "point" out of our 75. It can be surmised, therefore, that Determination costs more than one point. Let's think of it this way.

The Glanzfaust has 44 accuracy. Subtract that from 75 and we have 31 points left. The only other stat is Determination, so it can be seen that the remaining 31 "points" are in Determination. However, the stat says 22. This is because Determination costs more than one point. Let's discover just how much it costs.

Divide the 31 points assigned to Determination by the 22 it becomes and we get 1.409. Let's round this up to 1.41.

We can additionally test the Book of Spades. 75 "points" minus the 31 Crit we have is 44 points. 44 points assigned to Determination divided by the 31 we end up with is 1.419. Quite similar to our number from the Glanzfaust, yes? Let's take a mid-range out of both of these and declare the weight of Determination as being about 1.415, give or take a step or two. The actual number is probably more precise, but this will do for our simple calculations.

This means that every point of Determination on your piece of gear costs 1.415 points out of the amount of "points" allocated to that piece's secondary stats. Let's redo our math with these weights in mind.

The Glanzfaust: 44 x 1.0 = 44 Accuracy and 22 x 1.415 = 31.13 Determination = 75.13. We can round this down to 75.
The Book of Spades: 31 x 1.0 = 31 Crit and 31 x 1.415 = 43.86 Determination = 74.86. We can round this up to 75.

As you can see, these weapons with Determination have 75 secondary points attached to them after all. Now, let's redo the 44 X + 31 Det equation you're disputing, using, say... Crit, as the X.

44 x 1.0 = 44 Crit and 31 x 1.415 = 43.86 Determination = 87.86. We can round this up to 88 if we want. This number is clearly higher than 75, the number I've just proved is the cap for i110 weapons; even those with Determination. Therefore, it will very likely not be the case that we can actually have 44 of a 1:1 ratio stat and 31 Determination at the same time. The weights won't match up with the intended total of 75. Novus Weapons with Determination would be unequivocally better than weapons without it, and I doubt SE is stupid enough to let this happen.

My theory is that infusing 31 "points" of Determination into a weapon will give you 22 of the actual stat at the moment of the Novus upgrade. Alternatively, it would be cool if we were given the choice to go ahead and have 31 Determination and reduce any other stats on the weapon accordingly if we wanted. This higher weight, however, is no excuse to let those who choose Determination infuse fewer materia into their scroll. It would be unfair if some people got their Novus faster than others just because they chose different stats. Everyone has to infuse 75.
