Ok well I just loaded myself, my mules, and even my brothers mules up with goods to hammer out 97-99 cooking.
I started at 0% moon, no support, no +cooking skill on Lightningsday. Crafted all the way thru darksday. Once I hit 98% skill, I faced south (supposedly to up the chance of breaking/difficulty). It took me 66 synths to get 2.0 skill. So that's about 30%, roughly 1 gain out of every 3 synths. Mugwort is down to 30k on Bismarck, so that helped a lot.
Now to load myself up with cursed soup ingreds and go on a CN bee slaying fest! :grin:
