You have certain chance to craft, shown were the old WORK function was.
Then, when you DO get a chance to craft, you craft a certain item. Trade good is 100%. Everything else is percentage based.(Aka I had 2% for my straw hat, so every craft chance, I have a 1/50 chance to make a straw hat.)
Seems WAY to low. Either increase the chance to craft way way up, or the item chance up more.
