No problem! The boards are a wild jungle and we can all recognize that people spout nonsense in support of their interests. I make no claims about your motivations at all.
If you actually know what you're talking about, that's certainly one way to gauge the direction of the pps. What I have observed is that very rarely do predictions turn out, I imagine it's that the underlying statistical sample is distorted by multiple, unpredictable artifacts (in particular in startup biotechs with no product on the market).
