I was just about to ask if we could move to my wall, lol.
Its also actually fairly easy to calc the difference in joules, for aslong as we have a reference, if not, we can always make an assumption. Like I said, the difference between a sword vs a karate chop should be in the thousands to millions. (unless I am way too stupid to compare the surface area of a sword vs the side of a hand lol)
Also, about the scaleing in question. Maybe I didnt really make the scenario very clear (its pretty confusing as is). Lets make it simpler.
A guy who used a (insanely sharp) sword to harm a building level character. (thats just an example. Its actually a guy who is at lest in the 6-B region) This guy now doesnt use his sword and overpowers someone else with his bare hands.
Would/should we just assume the same AP in both cases?
Try to ask DontTalkDT. He's really knowledgeable on such topics because he's very knowledgeable about the physics. He has also helped very much with the standards. He may not be really active, but still, it's worth asking him.
You can also try to ask Elizhaa. He's at least decently knowledgeable with the standards.
