[Pre-BB] MapleStory Formula Compilation

hey guys, i tested the formula, it works perfectly

level 54 leecher
level 56 attacker
monster : bellflower root (160 exp)

exp received by leecher
160 * (160/160) = 160
0.8 * 54 / (54 + 56) = 0.393
0.2 * 0 / 160 = 0
160 * (0.393 + 0) = 62.88 = 63 exp (round up)

bonus exp 10% when party has 2 members including you
62.88 * 0.10 = 6.288 = 6 exp (round up)

edit:
strange... isnt this like 60:40?

63/160 = 0.393 (which is around 40% exp)
