I don't bother much with exposure, etc. Did you note Saint Ansel's quote of Minor White? When AA asked MW for data the reply was "the camera was faithfully used". In that spirit, I record the reasons for the decisions I make. The f/stop and shutter speed, etc. are really not very important - unless it's going to stay the same and I need to go back. That sometimes happens indoors, but almost NEVER outdoors.
I record my light readings and camera settings so that when I do something wrong...or even do something right, I'll know why...and perhaps even avoid the mistakes and repeat the successes. My notes are part of my learning process. I am constantly tweaking my exposure & development to match the changing parameters of my carbon printing.
I see the benefit of recording the "Why", but I'm afraid that I'll keep those as mental notes.
