All the animations I mentioned should still be the same as Native.
If you use outfit view and look at the stab and the rightswing of a 1h, you'll be pretty sure that there is no 42 range difference. Sure the actual reach of the stab is a bit longer than the effective, damage dealing, reach, but that 42 reach difference is just not there, not even close. I bet that if you would try hitting a person, even if it glances, the rightswing would hit before the stab would. One utterly wrong value renders the entire data rather useless.
