It sounds like 90% grit and 10% magic trick, but you were an instructor so I’ll take your word for it.

I still wish to believe that the crème de la crème, or the top 0.1% of the karate world, can muster enough force to break concrete regardless of any tricks.

I didn't magic trick in a pejorative sense. Just pointing out that there's a specific technique to being successful at it.
