This calculator models how people slow down in their muscle growth as they become more advanced, and get fast results as a newbie. The formula is based on 1 hour of AI research, so it is not authoritative and could be much better, but it's a good start to figure out how fast you will grow.
We use the concept of FFMI (Fat Free Mass Index) to model how much muscle you have, and how much you have left to grow independently of your body fat percentage and height.
