Rune Growth and Chara Growth

[dbemont]

I gather that Rune Growth ratings refer to the speed at which Rune Knights and monsters gain experience. And that Chara Growth refers to the speed at which Rune Knights gain Rune Power, in order to command larger armies.

But does anyone know by how much? Chara Growth, in particular, is a pretty big deal if it means that some inexperienced Rune Knight will quickly gain a lot more Rune Power. But if it's a marginal difference that maybe ten levels from now might be a difference of one additional mid-level unit, then it's not worth prioritizing.

First off I want to point out that I'm 100% convinced that these terms should be actually translated the other way (since it would make significantly more sense).

That said:
Character Growth -> Avg Rune per level is thus (Not every level is this exact amount, but on average it should be this, generally only +/-1)
E - 3 (Yes, E Exists... Finrall is gigatrash).
D - 4
C - 5
B - 6
A - 7
S - 8

So as an example, Rubino starts at level 5 and has 215 Rune Power with an A Growth.
By Level 30, he should, on average, have 215 + 25*7 = 215 + 175 = 390 Rune Power.
And sure enough, he does: https://imgur.com/a/Qly43CB

On the other hand, Mu'ah from Guilome starts with more RP (242) at level 21, but has a C Growth. So by 30 he'll have less than Rubino (242 + 9*5 = 287 avg RP).
