Depends on what I'm cooking. If it's baked potatoes or a roast or something that has a longer cooking time, I don't even wait for it to preheat. That just wastes gas (or electricity if it's that type). For something with a shorter cooking time, or that needs to be crisped, then I preheat to the beep but not usually beyond.
If I'm using my stone for bread or pizza, I preheat for at least 30 minutes after the beep.
