The assumption of monotonic benefits in the deliberate practice framework, suggesting equal progress for equal practice units, is likely incorrect.

“there is something called the monotonic benefits assumption and essentially if you have two people have never done something for every equal unit of practice they should progress exactly the same amount so it's everyone's practice response is the same is one of the assumptions underlying it and I start how can that be it's not to say it's not would be an interesting conclusion rather but how could that even be the null hypothesis it seems so counterintuitive”
