Indeed, like WWI aces would say, “altitude is money in the bank, and speed is money in the pocket.” Alpine skiing, in essence, is like flying a powerless glider, trading altitude/elevation for speed, and vice versa. Sometimes we need an insight to break out the conventional wisdom. In their example, the turns are started out by travelling sideways from fall-line, then turn into fall-line, then traverse, so the turns are accelerating first toward fall-line, then after cross the fall-line decelerating. Not just that from acceleration to deceleration is a complicated maneuver, and it is, in fact, a brake! To ski like those WWI aces said, dive straight down (follow the fall-line), any turning out speed will be slower than the initial speed, so, it is much easier to manage, as it is only deceleration part of the turn. Down-weighting to turn, speed is your friend.
