How is efficacy determined?

I'm just wondering how efficacy is determined. Like say, when I remove a product and 1 non beneficial irritant is removed, but 4 beneficial ingredients are removed as well, why does my routines efficacy rating actually go up, even when I am losing beneficial ingredients?

The routine efficacy also takes into account the number of products. Most efficacious routines in practice include a limited number of products and ingredients to deliver results while minimizing the risk of irritation. I hope we will be able to add more detailed explanations and routine guidance in the future
