Even 30 ft is amazing.
I'm convinced of what one of those films briefly mentioned (I think about Honnold), which is that people capable of breaching that mental barrier may be either missing a part of the normal brain activity or have abnormal brain chemistry. Something in their physical brain is allowing them to not fear what the other 99.999999% do. And that's not meant to be disrespect to them at all, as they still put have to have a crazy amount of work ethic, strength, bravery, etc. It just begins to explain how any human can actually brave such absurdities. The Alpinist guy was literally going up a wall many times larger than the El Cap routes...with ice and all. It was just so insane.
