All the comments except for one in that thread were just people making up numbers out of thin air. The one comment that had some data is from 2009. They couldn't even name the source, but even if we assume the data is good, there's been an explosion of climbing gyms since 2009. The number of good amateur climbers has increased massively because of that, and the average grade people are able to climb has risen because of the training opportunities gyms provide. > Chris Sharma was climbing for a year before he was doing the hardest sport routes in the world, but that isn't most people. That's true, but 5.12s are not even close to the hardest routes. They're hard, but totally manageable for a dedicated climber.
