Forget your conventional oven rules and seriously look at the instruction for compact convection cooking. There are lots of sites to help you retrain your mind on cooking. Even the manufacturer usually has good tips for their units. If you are baking hockey pucks, you are the cause. I have used an "air cooker" for years and a combination convection/microwave in the RV. If I want baked pork chops, it's in the Coach, biscuits the same thing. I am not a bread baker, too many specialty bakeries around me. Cookies and cupcakes are a snap, soft or crispy.
Go back to school and learn how to use your new appliance, and forget your old rules.
