Another attempt at measuring skiing

By now, it's clear that vertical drop alone doesn't quite fairly measure skiing in terms of skills, intensity and energy expended. It's only one facet of the whole picture.

It certainly belongs to the skier's dashboard, but must be considered along with speed, terrain grade, snow conditions (groomed, bumpy deep or crud snow) and snow qualities (light powder, heavier snow, slush, etc.).

Wow! That gets complicated. Just study this table, tell me if you get it or if you would have computing the whole thing differently!
