I would add that you don't have to use the reading on the incident meter to make the shot. If you know that the scene is high in brightness range, and you want to fit it onto your printing paper more easily, you can overexpose and underdevelop. You can also do the opposite in the opposite situation. With an incident meter, you will get best results if you pay close attention to brightness range and make these changes as needed. So, they are not completely idiot proof...but definitely much more so than reflected meters.
