I’m skeptical of “breakthroughs”. They’re usually accompanied by sales pitches.

It’s also worth distinguishing between “new” to the general public and “new” to elites like the Norwegian Nordic ski teams. For the former, there’s plenty that’s “new”. For the latter, not so much. Lucky for us, Scott and Steve are in the latter camp.

Slightly off topic, but I think this excellent post by coach Steve Magness speaks volumes about sticking to fundamentals, which is where we see 99.9% of all gains.
