James,
Think back to the original UFC. How many deaths were there? Yes, if memory serves, the Sumo guy had his jaw broken by a well placed kick, and I think the Savate guy broke his hand. Just think about the striking, ignore the grappling.
Yes, there was no biting or eye gouging allowed, but how many people involved were permanently debilitated? None, and that was the first time that people boasting, "If I were to really let my attacks go, people would die" had an opportunity to see if that was true. What did we learn? Many of the techniques we thought were deadly turned out to be nullified by fighting in the adrenal state.
Now, turning our attention to RCSF, this also turns out to be true much of the time. The midline horizontal shots we are taught are so deadly in many systems really don't do much in the adrenal state. One of my post-gathering rituals is to go home, take of my shirt and have my wife help me with injury inventory because, frankly, MOST of the shots I don't feel during a Gathering. This is not to say that I haven't been hit hard or that the organization doesn't boast skilled fighters because I have and it does.
Body shots, if they are only leaving a stick hickey, are not severe enough in the adrenal state to be a worry. This is one of the gifts of fighting in a Gathering, rather than training for and speculating about things like hand shots, I have expereinced hand shots.
Yes, there are injuries. Yes, I have seen broken bones and blood. I'm fairly certain I have fractured some small bones in my right hand at a Gathering, but I never gone to the doctor (yet) because in a short time, the pain went away. After one of the last tribal Gatherings at which I fought, I had something like 10 fights (not counting knife fights) in two days, and I went and took a Kali/JKD class the next day. Why? To prove something? To be a "tough guy"?
No. I went to class because the more effort I put into making a Gathering seem like a semi-regular training event, rather than a life-threatening test, the less I have to focus on nerves and the more I can focus on being present during the Gathering, enjoying the tribe members (because, and this is the truth, DBMA attracts some of the nicest, most authentic, funny guys you could ever meet), and enjoying the special nature of the fact that only a handful of people in the world want to do RCSF, and I get to be one of them.
Again, not to be a "tough guy", but to be in that elite number, and be able to bring that self-discovery to my life, my family, my classroom (I teach high school), and my martial arts students.
The human body is capable of handling a lot more than we think it can in our crucible-less, initiation-free culture. That's what I've found to be true.
