"The Preface" is counter-productive

After re-reading the preface, I feel like exploring Wordsworth's supposed "process of composition," since it was the hardest for me to pinpoint what his process actually entails. From what I could gather, it consists of 4 parts: perception/inspiration, recollection, analyzing that recollection and finally writing about that perception. According to Wordsworth, it's during this recollection phase that you can analyze your inspiration and realize the emotion you felt, but by doing this, doesn't that take away from the spontaneous aspect of emotion? If you sit and contemplate your emotions before writing about them, the end result is probably different from that of the original one. This brings up numerous inquiries, such as how spontaneous is Wordsworth experience at Tinturn Abbey if he sat and pondered this emotion for several hours, maybe even days? How accurate is the emotion he felt in that moment at Tinturn Abbey if he had to put his emotions into context? It's like waking up from a dream and attempting to recollect it later on: chances are, if you don't write down what you just experienced as you awoke, you're going to miss some key elements. And that's how I feel reading now reading the Lyrical Ballads with the preface.
