If there is so few people that get it right, maybe the problem is that the system is not adapted for the vast majority of people and the reality of the work life, and other options should be explored.

But there is always someone claiming that everyone else get it wrong and blablabla.

But someone with a MBA in a closed office is pushing that shit all the time, and everyone that has to use it roll their eyes because they know damn well that the only thing that will matter is those damn story points, and the people will game the system because that’s all that matters to those that don’t use the system, and you will hear about that other team that always finish the tasks in their sprint.
