don't worry about it, i was just idly curious. there is a sort of philosophical aspect about building models: when one should discard an outdated model. i understand that as you are going along, you learn more and the newer models supersede the old ones because you are confident that the new ones are simply better. in other words, you think that there is not much value in old models because all important aspects you learned from them are incorporated in the newest one.
The old model pointed me in the right direction, but it was incomplete in the face of adaptation. In retrospect, I didn't heed my own advice to "fail fast", I hung on too long. It is very difficult to do when you don't have a complete picture. For example, there are systems where on average they underperform the SPX in any given five month period in two years, but over the entire length they handily beat it if you hang on in a disciplined manner. How did I know this was not the case in "FV"? I only realized this when my understanding became more complete. Then it was obvious. In fact, it is amazing now that I have a more complete picture just how efficient SPX is in the short term.
"NFV" went out at ~1175, with SPX @ 1,208.67. That is a substantial divergence. I don't know what to think.
