I remember finding an equation, or set of equations, to calculate the base (starting) quality of a craft depending on whether the materials were HQ or NQ. I know that if you have all HQ it will be 50% of the total quality (shows as 15% on the quality bar) but it's when there's a mix I have trouble.

Obviously if I already have the mats I can just use the craft log to check but if I don't, or if I'm not in the game, it isn't possible. Can anyone point me in the right direction for the equation(s) or a way to calculate the base quality? I have searched quite extensively with Google but can't find the place where I saw it.

Thanks. =)
