I replied separately, but this is being written about because up to now, every last elite climber said 'nope, I'll 100% die on this one'. Well, perhaps there were aborted attempts (I'm not aware of any), but you abort when it becomes impossible, ie death is looming.

People can quote stats for Himalayan climbs and the such, but a climb like this lacks meaningful statistics. It is so far from a trudge up Everest, and unequalled, that I don't see how to assign a stat. Right now it stands at 0%, which is probably not the right number.

I dont have hard data but definitely nowhere close to 10-20% that’s just ridiculous. Somewhere like 1 to 10000 on routes with very high objective danger would be my guess
