[Pre-BB] MapleStory Formula Compilation

Anyone know approximately how much Chakra heals?

From some code Fiel showed me, it looks like:
Max = (20/3 * LUK + DEX) * Skill / 5
Min = (10/3 * LUK + DEX) * Skill / 5

But I have no idea if that's even reasonable or not.

The formula I read on a JMS website is:

Max = (LUK * 6.6 + DEX) * 0.2 * (Recovery%/100 + 1)
Min = (LUK * 3.3 + DEX) * 0.2 * (Recovery%/100 + 1)

(I know it's not many; I only wanted to check if LUK means total LUK with equips back then)
