True, but that did have 3 rounds of feeling mostly like Rua won. So although you could end up with 50-45 Rua easily, you could also see a 48-47 Machida. Whereas this was fully like 90% assuredness, almost unarguably, the most obvious 48-47 someone could score. It's like rolling three dice and coming up with three 1's, vs flipping a coin and having it land on it's edge. One's got a lot more avenues for failure, sure, but the other just shouldn't happen.
I'm too biased with today's scoring to fairly judge Rutten-Randleman, which is usually a big argument for worst title robbery. Edgar vs Penn 1 comes up a lot and Edgar-Bendo 2 is probably the worst title robbery ever, but one of the least cared about because of all the rematch syndrome LW had at the time. Worst in recent memory is Condit-Lawler though.
