What makes a potato recipe worth repeating, and does the format it's presented in affect that?

Potato recipes occupy a strange middle ground in the repeatability question. A dish like potatoes Romanoff, built on shredded starch, fat, and dairy, succeeds or fails based on whether those components are doing something specific together rather than just coexisting. The technique matters, but so does whether the method is actually accessible when you return to it weeks later. My question is whether the presentation format, a tested recipe with clear attribution versus something reconstructed from memory or loose notes, changes how often people actually return to a dish. Does a well-documented method increase repeat use, or does familiarity eventually make the documentation irrelevant?
