It's a guide for RAW users, it's only accurate if shooting finished files in camera. We are talking about the Pentax DSLRs of course, I have no idea how thehistogram is derived in other brands of cameras.
So far as I know they all use data from the preview JPEG, the same JPEG that's viewed on the in-camera monitor. So you are not only not seeing an accurate histogram from the RAW image, you aren't seeing the RAW image on the monitor, either.
