Um, no, I'm talking about separating the current "Cooking" craftskill XP into "Cooking" and "Brewing" craftskill XP based on what was crafted.
So if someone had 10000 XP in the Cooking craft, then after the split, they might have (for instance) 6712 XP in Cooking and 3288 XP in Brewing.
It's irrelevant though, because I'm not separating brewing out of cooking. If I did, I should separate paper making out too, and that's a whole other set of messes that I just don't think will add any real value to the world, nor will it truly change anyone's enjoyment of the craft(s).
