DB picks who fights who, and do it for reasons like views or to give a boost to their partner sight.
The question is whether they pick the
winners of those fights for those sorts of reasons.
I admit the fact that they are showmen that do lots of things for business reasons, rather than being disinterested academic scholars answering a question posed to them, means they are more likely to decide a fight because they want to get people upset if it'll get them more views.
However, I don't see the connections to pissing people off getting more views, and if it does, who to piss off? Is it any better to piss off Goku's crowd than Superman's crowd, or Spiderman 2099's? Is there any reason to believe that a policy of picking weaker winners gets them more views and makes them more popular?
By the way, Superman is hardly an obvious victory for Goku, there are plenty of fans with their
own calculations supporting a Superman victory.
When I have seen academics do these sorts of calculations, what I actually tend to see is far less convincing than DB. Often times they just pick out some isolated scene or factoid and do their calculations from there without even attempting to give their numbers context. The results often seem random and missing the point.
For example, one physicist calculated that Star Wars ships are weaker than Star Trek ones (despite being much more massive) because the energy scales given in Star Wars is orders of magnitude lower than what Star Trek ships are said to put out.
When DB runs such calculations for Yang and Tifa, I am not surprised Yang's tolerance for punishment is considered incredible given they picked the episode Yang's back fought a highway supporting girder and the girder was the thing that bent.
DB often chooses some illustrative event to run some calculations for both characters, but they at least make an
attempt to ground those calculation in the history and gestalt capabilities of the character.
I don't agree the winner in any of these wrong picks are so blindingly obvious it must have been picked by a dishonest judge. Also, the admissions you say Screwattack has made (I'm never going to get a link am I?) don't sound like admissions they have ignored their own analysis to pick a winner to garner more views or annoy certain fans. They basically sounds like admissions to running a show.
