absolutely------it's where some of your best learning will take place, if you find you made a particularly good negative and print, it's helpful to look back on some notes to see what contributed to it----the same if you make a particularly poor negative. Like JBrunner mentioned, LF is especially suited for it because a single sheet of film can be exposed and developed to a very particular set of circumstances that apply to just that sheet. For roll film, unless the roll is exposed to pretty much the same conditions of contrast, your development of it may ideally suit only a few frames, but less extreme differences can be compensated for in the printing phase, however to arrive at a satisfactory print.

If you are just starting out and learning the process, take lots of notes------but if I were to suggest the one thing you should take particular note of, it would be the apparent subject contrast that you subjected the roll to----and with film development, take note of your time and temp, always stay consistent with your temp, but you will learn that alteration of dev time adds another dimention of control to the final outcome. Generally speaking, increased development for low subject contrast and reduced development for high subject contrast. Keep note of these things.
