RowLists / MarkupGrids ScrollSpeed Field

I’m working with RowLists and MarkupGrids changing their Scroll animations by modifying the ScrollSpeed values between 0 and 3. I’m wondering about what is the relation of this value with the animation (timing, acceleration, pixel per second, etc.). Is it consistent throughout the Roku UI/ecosystem?

I only found info about this field in ScrollLabel documentation but it seems that does not work equally for grids.

Any info about that will be helpful to me!
