How Ligety finds his limitation

Up until today, Ted Ligety has dominated the field in GS competition. The question was how much more margin of superiority could he gain? Well, today, on a both steep and icy Val d'Isère run, he found out quickly when his extreme angulation suddenly became too much as ended up edging on his boots. We generally find the upper limit by an occasional failure and that's how we keep on becoming even better. Easy for me to say, right?
