One really never needs longer than 2-3 weeks, unless you prefer it. Enzymatic activity that occurs during the cure does not extend past the 2-3 week window without an external impetus.
When I was a beginner, I would often do cures on the order of months. The only thing that changes is I started caring more about my flower. Harvest cleanly and smoothly with minimal free salts and minimal chlorophyll, dry slow, and then you'll quickly find that ~2 weeks cure is that sweet spot for the S-tier za. These days, unless I mess a run up and have dirty flower, I would never need months for a cure.
Try it for yourself. Like, for example, most folks will tell you to cure in a cold environment. Did you know that enzymatic activity is temperature gated? You have to breach a critical temp for a critical period before enzymatic activity is off to the races, right below 80F.
Like everything with this plant, there are many ways to cross the finish line. There is also a divergence in the homegrowing community and the academics/science folks as far as curing timelines and knowledge.
