There is some math missing. I don't remember the name now, but when something has a 2:1 positive to negative ratio of votes but only has 3 votes, and another thing also has a 2:1 ratio but has 400 votes, it's not the same ratio.
My money is still on Hannibal and Alexander as being the best generals. They both fought and won battles against huge odds. And invented amazing tactics. You know that saying: "how much a smartphone costs? A few billion for the first one in research, and few hundred for all the others." The only thing that I heard Napoleon invented was that defeat in detail thing. I invented that on my own when playing starcraft as a kid :/ I think napoleon truly took advantage of the idea of the republic where each man owned himself and had to serve for citizenship. But I'm no expert, so yeh: some math seems to be missing.
