Just with every model - further filtration can greatly affect the total return. We project the returns of the BP models based on the notion that a user will have proper diversification of picks and not just have a few notes. When you begin to further filter the already filtered criteria it technically invalidates the model because it becomes a new model entirely. With that being said, not everyone will agree with me 100% =). That's what I built in the ability for our users to apply additional filter criteria. I myself invest in the BP Aggressive model with one of my accounts without filtering and I believe that Jon does as well.
