We have written down what we would have to earn

We are not claiming this model is predictive. It ships free, as a labelled second opinion, with its record published in full. If the 95% confidence band on our win rate against the sector benchmark sits entirely above 50% over at least 200 sector-gradeable calls, we will have earned the right to describe it as predictive. Until then we won't.
