I noted the calculations from Smogon before I posted. They were also made months ago when we understood less about the damage calculation formula. They appear to have used Metalkid's damage calculator which I found seems to not statistically floor fractional damage until the last step when it should be done at every step, the one I use is X-Act's formula which does floor at every step. I am willing to believe that I am wrong however, and so I posted not a moment ago there inquiring about it.
I agree it isn't the typical set, but we also assume Rocks which might not be there, and that Skarmory switches in, which it shouldn't. If it can survive with a max/max EV spread, it is important and should be noted! Also, "85-103%" is significantly different from the "is OHKO'd" claim your previous post made, and I thought it was worth clearing up. I'm not saying the assertion that skarmory can't stop Lucario is wrong, but people should not be misled and then surprised when an unexpected result occurs.
Don't assume that 'because it is on smogon, it cannot be wrong' or 'it is the best.' New ideas and sets are being developed and old information and sets are found lacking in the face of change and discovery. Also don't assume I am claiming that you think that way! Its just a word of advice. I sometimes use a Miltank spread which is basically Blissey Lite (discouraged by Smogon), but EV'd to let me cripple and kill non-spec'd Gengars who think they can just come in and take me out with Focus Blast. I found it worked well in the PC battle forums, where I came across Gengar in almost every battle and was able to use a non-obvious set on one of my favorite pokemon to stop it (unlike something like Weavile where your intent is obvious). Smogon's analyses are a great start, I love them to death, but they are not by far the final stop when it comes to pokemon.
EDIT - Whoo PC was down for awhile. X-Act replied to my PM on smogon and confirmed the damage.
