So this has been something that has popped in and out of my mind as a question, i have seen some points about it being harder than usually expected to knock someone out with bare hands/beat them. (which is true, so is the reverse sometimes) So i was curious if anyone could put a percentage on the like hood of causing a concussion on someone. (at least enough of one to have them cease being a threat) Also i forget, what is the average amount of force needed for a concussion and the different stages of one? And then what is the average persons punch strength and then compared to someone who does MA/combat sports. Or open hand. there is nothing really to this, i have seen some videos of someone being knocked out with one hit, and others where they take like 5 and don't get knocked out. So its kind of a randomness aspect to it, just wanted something more scientific if it currently exists. Obviously for it to be scientific there needs to be a stat for trained to untrained and different levels of concussion and different stages of readiness for both parties, so more than one stat needs to be present.
