Just How Hard is Olympic Sport Climbing?

Confession: sometimes I watch IFSC Boulder World Cups and think, “Man, I could probably stick those moves.” (I could not, in fact, stick those moves.) But in my defense, without grade estimates, and with only a few minutes of airtime on TV, it is hard to comprehend how difficult these problems really are. And the world’s most elite climbers tend to make V12 look pretty dang easy.
