MP / PIE Formula

[Yonko]

Do you have any idea what the SMN multiplier is.

Using your SCH formula I get the following

Actual Piety Additional Total from formula
3012 214 1619.98 3149.98

Assuming the same base value as SCH the multiplier should be ~6.92523. It is possible that the base is different for SMN but it shares the same class as SCH so I would expect it to be the same.

Also where are you getting your base values from?

Looking at the HP formula found http://valk.dancing-mad.com/tables/attribute-table/ (scroll to the bottom) I'd think there is an overall formula.
For reference HP = Base HP + (14.5 x (VIT – 202))
And Base HP is 85*(class/job mod)

I'm calculating the base values myself, working backwards after I've already calculated the MP per PIE.
These formulas do also assume that you're calculating for a level 50 character.
I'm sure there's probably a more correct, more complicated formula than mine for calculating MP, but mine seem to work and I don't care enough to look further into it.
If anything I'm probably oversimplifying it by using a larger base MP and not using some kind of (PIE - 90) in a similar way that Valk uses (VIT - 202) for HP calculations. Difference being that the 14.5 HP/VIT doesn't seem to apply to the first 202 VIT a player has. Otherwise every character would have 2929 HP minimum at level 50. And this is easily seen to not be the case.
There probably IS a job multiplier though. After figuring out the BLM Base MP I noticed it was 66 MP higher than WHM, which was 66 higher than SCH. I may revisit this later on.
