When should I use the Natural Release Feature versus the Quick Steam Release Feature?

The Natural Release Feature is preferred when cooking foods like stocks, sauces, and certain large cuts of meat which will benefit from continuing to cook as the pressure and temperature drop naturally. Do not use Natural Release with foods that can overcook easily and quickly. Use the Quick Steam Release Feature for immediate pressure release, but avoid it for foods with a lot of liquid as there could be an overflow. (Pages 11-12)
