Lee, I'm surprised you don't keep notes.
I keep date, exposure#, paper, size, developer, dilution, magenta(color enlarger), fstop, time, height, soft time, brightness,hardtime(Zone VI cold light head) toner, dilution, toner time, bleach time, as well as boxes to illustrate burn and dodge times
I find that the next day if I didn't like the final print or months later, I could get exactly the same or very close. It sure takes less time than starting over from the beginning.
I wonder what everyone else does.
