[Pre-BB] MapleStory Formula Compilation

Bare Hands:
MAX = (STR * J + DEX) * Weapon Attack / 100
MIN = (STR * J * 0.1 * 0.9 + DEX) * Weapon Attack / 100
ATT equals floor((2*level+31)/3) and is capped at 31.
J equals 3.0 for Pirates and 4.2 for all 2nd+ job Pirates.

what does the bold means?

does the value ATT is calculated before being used in "Weapon Attack"?
