No see, I disagree on the range, Olimar loses pretty much all of his effective range here, because of the priority issue. That's the range of all three of his smashes, because dair, nair, fair, and bair will hurt, knock away, and possibly kill the pikmin while still being able to continue and hit olimar, that also means Olimar's pikmin latch isn't going to get him anywhere, then all of Olimar's 4 directional aerials get outranged and beat by Luigi's. Olimar can't grab an airborne opponent and the pikmin is still vulnerable. That leaves Olimar with not much left, mostly his moves that use Olimar himself, and if you consider the quality of those none of them have a whole lot of range at all(even though uptilt and nair are quite good moves for olimar on their own). I agree on the tornado, Luigi's tornado will dominate an Olimar who doesn't know any better but not so if the Olimar knows what's up, but weaving in and out with aerials or using Olimar's range shouldn't be possible either.
I don't contest the point that this isn't a "pick luigi and auto win" completely in his favor match-up or that it's possible for good Olimar's to still pull through, but if we went back to that chart, I'd bet Luigi deserves a blue check and just possibly a big blue check.
