Not having a clear-structured and measured method doesn't equal to not having any method any relying purely on your subconscious. Sounds more like you were parsing through the code and lots of typical hints such cesspools usually have made it pretty clear very quickly.
Perhaps. But I page through the code faster than I can register the details. Just the 'shape of it' gets through. Not really time for parsing. So some subconscious element must be in play.
