[Pre-BB] MapleStory Formula Compilation

If the equation is of the form:
-> (STR + LUK + DEX * K) * (1.5 + SkillLevel * 0.05) * damage%, then K must be contained within approximately [0.00070, 0.00075].
-> ((STR + LUK) * (1.5 + SkillLevel * 0.05) + DEX * K) * damage%, then K must be contained within approximately [0.00116, 0.00124].
-> (STR + LUK) * (1.5 + DEX * K + SkillLevel * 0.05) * damage%, then K must be contained within approximately [0.00000151, 0.00000163].

These are what I think would be the most likely cases. Alternatively, there is some mistake or something not accounted for.

Does defense affect Ambush at all? I would assume not, but to make sure.

Follow up:

GameMX's base damage with no DEX component is 714.984, or 714. With 132 DEX, the damage is still 714, so it must add no more than 0.0001212 damage per point.
EtherShade's base damage with no DEX component is 830.907, or 830. With 122 DEX, the damage becomes 831, so it must add at least 0.0007622 damage per point (and no more than 0.0089590).

I don't believe that the difference in damage per point between the two characters can be that dramatic, no matter where DEX is placed in the equation, and even if it were, it's such a small effect in the first place (we're talking over 1000 DEX to add a single point of damage) that it might as well not be there.

Perhaps there was a mistake and something was equipped that shouldn't have been. I'm assuming that Ambush has no DEX component unless further evidence shows a clear association.
