The amount of points doesn’t matter. It is after all the resulting curve that counts. The curve itself is a representation of the mathematic to create the curve, and this takes the position of the points and interpolates from these points.
To go more into detail, a reason why we bake out the curves in one point per frame, for example, is given in the fact that those calculations are not always based on the same formula. To get “same” result after exporting an animation, this is one way to go.
The amount of points is more a question of how one likes to manipulate the curve. Less points will result in more power to a single point. More points will result in more detailed control.
The term ease is not defined mathematical, it is from application to application perhaps different, hence my initial question if I get your point. It was not meant to put at all in question if I’m aware of that option.
All the best
