An interesting way to look at writing novels, but I far prefer the novels that have the plot worked out before the writing starts. I can always tell these because everything integrates so well with everything else and it feels whole.

Novels that 'start on page 1 and slog through to the end' usually read the same way. They ramble and they get lost and eventually find some kind of ending.

Novels that start somewhere, then work out different pieces until there's a whole novel would seem to be in the same category for the reader, but probably more fun for the writer.
