I think there would need to be the case of a serious series permanently in the back of the magazine (bottom rankings) that survives for several years to provide evidence for the ranking wars to be completely bananas. Or a series that somehow collapsed to the bottom and somehow didnt end for many years (that wasnt in its ending arc).
Bleach, Jaguar, etc. Bleach was near the bottom even near the end of the Aizen stuff.
Almost the entire base rules from which we perceive the rankings to be are established on the suggested system in Bakuman, which showed it back in 2008.
Still believing so firmly that this is THE way to read the table of contents is predicated on two things: 1) That Bakuman was being wholly honest and 2) that nothing at Jump editorial has changed in eight years.
People take the rankings too seriously when in the end the content order is subject to editorial whim.
I think its been stated that some of it is just editorial reasons as opposed to being the factual order of the rankings. There's also the fact that why the fuck would the editors give a fuck if a Top 10 selling series didn't get stupid votes? The votes aren't actually meaningful to anything - what's meaningful is whether they sell volumes, and those rankings sometimes, but don't always correlate with that.
The fact that Shokugeki no Soma (allegedly) finished last in those rankings by itself indicates that they're bullshit. Shokugeki no Soma sold close to 4 million volumes last year alone. People keep treating the content order as some kind of Nielsen rating when it doesn't work anything like that either in function or effect.
I mean, even to the extent someone wants to argue it shows how well some arc was received it's nonsensical. We don't know even know how many votes get cast. Even going further down the rabbit hole and you take all of that stuff seriously, Shokugeki finished 3rd, 3rd, 6th and then last in the last 5 issues where it wasn't given color pages. Sure, you could argue that this trend means there was some specific chapter in a series of chapters that the fans didn't recevei well, but Occam's Razor suggests that its more likely the rankings are dumb and/or don't work the way fictional work Bakuman (which of course, had an incentive to play it up for drama) said it did.
