The remembering to log is seeing the paper/book on the night stand when I go to bed. So it's mostly only for daily tasks. Finer grained logging doesn't happen because of the remembering and inconvenience.
The analysis hasn't been anything rigorous or long term. More eyeballing the data and checking for general trends. I'd like to be better at logging, but it's been too hard without an app to help remind and structure the data.
I tried using Google sheets or plain text on my phone, but the friction decreased my motivation to enter the data.
