You may find that most of the information recorded will only be valuable to you at certain times, and in certain circumstances.

Situations like when you are learning to expose and develop and print your own film, and when you are testing new to you films, equipment and other materials and procedures.

So it would be a good idea to have both a means for recording the data in those circumstances, and to have developed the habit of recording it.

Once you have dialed in your procedure, equipment, materials and understanding of the process, you can decide whether or not to continue with the data recording and, if so, when.
