Diminishing returns for number of classes
Just a general question: at what point for adult beginners do you think taking more ballet classes will not help anymore? I often hear that no matter what cross training you do, the only way to improve at ballet is to do ballet, but at what point is it better to cut down on classes and replace them with cross training? (In a scenario where theoretically the adult ballet dancer has unlimited access to classes.)
For example, I’m currently taking class eight times a week (which I am very lucky to do since my current job allows me the flexibility to do so) and have the possibility of adding more. I think stamina/endurance-wise it wouldn’t be too taxing to add 2-3 extra classes per week, but I’m wondering if at that point it would just be better to replace time I would spend in class with cross training.
EDIT: More context:
I'm 23, and I'm currently at a stage in my life where I have the time and money to go all in for 1.5 years, so in this time I want to get as good as I possibly can. I would love to do some sort of dance-related thing in the future (I don't want to be presumptuous and say professionally) but when I get into hobbies I usually have an all-or-nothing attitude. I take one day off per week, and the class levels range from beginner to intermediate (taking classes with people aiming to be pros). I am not currently on pointe.
