Likewise for this part: "The first two days involved about 6,000 vertical feet of climbing, 60 meters of rope at a time." No "regular human" is even making it 50 feet free climbing up a vertical wall, let alone the technical skill required to clip the rope, place protection, and manage equipment while climbing and working with your partner.
It's really easy to underestimate this stuff, especially if you've never actually tried rock climbing or done high altitude stuff before. It may look easy, but at around 15,000 feet it gets to the point where even the most physically in-shape person cannot walk more than a few steps without having to stop and take a breath, let alone climb a vertical wall.
Likewise, rock climbing might look easy, but go to a local climbing gym and pick a 5.9 or 5.10 (which are about medium difficulty) and unless you have past experience climbing, I guarantee you won't even make it halfway up. And that's at a gym, where everything is easier, and you don't need to worry about placing your own protection or carrying ropes.
Part of the reason for this, I think, is that Hollywood and TV depicts ludicrous levels of acrobatic and athletic capability as the norm; apparently normal people in movies are depicted catching falling people one-handed, outrunning explosions, and so on.
Climbing, even at an enthusiastic amateur level, is much harder than non-climbers believe, and I think your suggestion that readers try top-roping a 5.9/5.10 to get some idea of even beginning climbing difficulty is an excellent idea.
I cannot even imagine the level of dedication and expertise it takes to do this sort of feat.

Regular human beings would die 100% of the time. Not 80.
As for 'dice rolls', it depends. In climbing there is "objective danger" - danger you cannot really control, like your route passes under a serac that collapses frequently, and "subjective danger" that you can control - you step on a loose hold and fall. They spend months planning, trying to reduce the objective dangers as much as possible, and of course years of training to reduce the subjective dangers. Summarizing all of that as a 'dice roll', while it might capture the percentages of particular high risk climbs, seems to miss the mark a bit. Spend a night in a climbing hut, or hanging in a tent/portaledge off a mountain side and it's endless talk about this sort of thing. How to master your body, the terrain, and often most importantly and hardest, your mind.
Not sure if you'd say "a lot of regular humans" have a Nobel. There are a lot of laureates out there, but I mean are they regular guys?
If you know more than someone else, that's great, but in that case please share some of what you know, so the rest of us can learn.

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.
