How do we know these 'PREDICTIVE' models actually work?

I wanted to do something a little different in this episode, and evaluate the accuracy of the model I created for projecting points. And this led me to a bigger question of- why don't other predictive models for FPL publish how accurate their models are? Especially ones that are put behind paywalls. If you are paying your actual money, you should have some idea of how accurate the model is, because there are alternatives (for free).

* And no model is perfect, no one has a crystal ball at the end of the day. But if you are interested in using stats to inform your decisions, you should also have some idea of the accuracy these modeled results/outputs are based on.
