Sure! Its easiest to think of this as an equation actually. Put the ski on a graph so that the origin is where the rocker starts in the side profile.
Classical rocker, at least for us, had the rocker emerge from the ski at an angle (say, like the equation y=x/4 or something), and then after a distance you would have a set tip curve.
Elliptical is just that, its an ellipse. It gradually turns sharper and sharper. If we're talking tip shape, its like the lower right quadrant of the ellipse in this picture.
So the theres no real point where the rocker stops and the tip shape starts, they just slow into each other, and the rocker starts very gradually, so theres no hard point on the ski, making it way more stable since everything just transitions into the shape, instead of abruptly.
Theres way more behind this, but I dont want to give too much away.
