[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.

Defense shouldn't affect it. It always produces the same amount of damage per hit.
