Beginners build muscle fast, but advanced lifters gain slower. That's why experienced trainees should gain weight gradually to avoid excess fat. A slower pace means shorter, less painful cuts later.
The more of a new beginner you are, the greater is your potential of building muscle over a certain time period. The more advanced you get, the slower it gets in terms of building muscle mass. And therefore you also want to have a slower rate of weight gain over time or else it will, a lot of it will just be fat mass. And when you then at one point like to go on a, on a cut, then it, it will be pretty painful and it will be a very long cut that you have to get yourself through.
