Usually we're in agreement on printing/enlarging matters, but I'm not sure I'm entirely with you on this. Suppose you pull out an old negative to print again, a complicated bitch of a negative/print with lots of burning/dodging, perhaps flashing etc. You would really rather start from scratch than have a set of reference "instructions" to follow that would at least get you to reasonably good work print relatively quickly? Of course I'm not saying you necessarily want to prefectly duplicate the way you had printed the negative before. You might tweak things, make improvements etc. But unless you are truly going to start from scratch with a completely new interpretation of the negative, why would you not want to make some use of the print plan you had originally come up with?
