I'm new to Android Architecture Components and I have read [this](https://medium.com/google-developers/viewmodels-a-simple-example-ed5ac416317e) tutorial. I'm interested in the part where it said:

Let’s imagine if we extended our Court-Counter example to have the scores for multiple basketball games. The games are presented in a list, and then clicking on a game in the list opens a screen that looks like our current MainActivity, but which I’ll call GameScoreActivity.

Let's say I have a ViewModel `MyViewModel`. And I want to create a list of this view model but I don't know the number of elements in this list until runtime. Is it convenient to create the view model instances inside a for loop? How many instances am I allowed to create? Will the number of instances affect performance?
