How we learn as adults is completely different than how we learn as children. You are much more conscious and self-aware then you were back then. Figuring out what you are actually doing at the piano versus what you should be doing is much more important than any particular routine. As your mental model of how to play improves you also have to develop the sensations and cues needed to bring about those results consistently. Education of the physical self and how it interacts with the piano to produce intended aural results is important at this stage. You might look into the Taubman method, Alexander technique, or Feldenkrais for example. Everyone is a little bit different in what they may actually need. Personally I found a combination of Taubman and Abby Whiteside's pedagogy the most useful.
