A little add-on to my post regarding time consuming sushi making.

An order came up that asked for 2 lillies, 2 blackberry jam, 4 cocoa beans and 3 hot peppers. I would receive a total of 203 XP points and something like 240 coins.

Another order asks for 2 sushi rolls and 3 strips of bacon. A total of 293 XP and 830 or so coins.

Sushi is way more time consuming than the other order.

How are XP decided? Or does the game figure you get a fair enough share of XP by gathering and crafting these things?
