I think what acrary is saying is that he entered the game with some preconceived notions and built a foundation to support them. Then constructed a model upon this foundation with arbitrarily forced measures (1 day, 2 days, etc.). He needed to be right in his assumptions for this elegant, but brittle framework to function effectively.
He now feels that he was not right in his initial assumptions and that a more ductile framework with less moving parts would have been much more effective, those less elegant in theory.
