There are multiple factors in survival. Qi carries more weight than Body in some parts of the Beast Wave because of what the Beast Waves actually are in the setting, but neither is the whole answer.
I do like the idea of the earlier outcomes giving a little more indication of what was missing though. I don't want them to turn into a checklist for the next outcome, since figuring out what actually matters is part of the progression, but there is probably room to make the result itself give you a better idea of where you fell short.
There are reasons for the difference in what you can survive at different stat totals as well. I have to be a little careful explaining that one because I would end up giving away more than I want to, but it isn't just the displayed attack power behaving strangely.
