French to English Marketing Sports / Fitness / Recreation ski catalogue

I'm translating ski descriptions and am faced with a way of describing skis that I have never seen before. I am familiar with radius (rayon) and sidecut (ligne de côte) measurements, but this is new to me:

Polyvalence de courbes
Le pourcentage exprime comment est typé le ski (petites ou grandes courbes).
La ligne de côtes exprimée en mm indique la largeur du ski en 3 points (spatule / patin / talon).

Then, for each ski description, you have something like:

Polyvalence de courbes
80% petites courbes, 20% grandes courbes
Rayon 20 m
Côtes 105/85/95.

The only thing I can surmise is something like "turn versatily", the ski being shaped for skiers who will perform 80% small turns and 20% large turns.

I am thankful for any efforts at help, but would appreciate references if possible, as this is something that appears throughout the catalogue and needs to be as accurate as possible.

Many thanks in advance.
