It depends really on the strip or test, etc.
If you have good negative storage setup, say each roll gets its own sheet. its easy to take a marker, give each sheet a unique serial number, and write a small number on each frame.
Start a print book like others do, and i just started, write sheet number and negative frame number down, and aperture stop, timer length, dichro head settings, and enlarger height.
If you have an image that needs dodging, etc, keep a print of THAT one, and use a magic marker to outline the area you need to dodge/burn, and write the timer settings on that.
