Of course, the problem with that is that if some of those highs turn out to be something you need and they're blown out, there's no way to recover them.
IMO, it is usually far better to shoot RAW and avoid getting the values compressed down to 8 bits per subpixel (JPEG) from the original 14. That way, you don't have to worry so much about the exposure.
