Based on timestamps on the pages this is likely a re-print of an earlier version of the book.
This list contains some of the hardest problems in the world, ever. Ticking anything in the top 30 is a noteworthy achievement. Anything in the top 10 is sick and a level of respect is gained unlike anything the world has ever seen.
The list is perfect and is not dependent on height or anything. It is dependent purely on strength, power and fingers of steel. If you don't agree with it you're wrong and you've obviously got a big weakness in your climbing. In fact you're just shit so leave me alone. I spent a lot of time compiling this list and disagreeing is fruitless as, like all climbers, I know best.
