Final Fantasy Hacktics

So I'm learning how to use FFTPatcher. I've consulted the page on formulas in the wiki. I'm just not sure whether I'm reading these formulas correctly or not. Here's an example:

Blind uses: 0A Hit_F(MA+X)%

Does this mean: "Faith(Caster's Faith * Target's Faith / 100^2) * (MA + X)"? And whatever that spits out is the % of spell success?

Edit: Also, to increase hit rate of the base spell, do I simply raise the value of X in FFTPatcher?

Solved: I figured out I was reading the formulas correctly.
