An error in the system of rating heroes in One Punch Man


I think that the rating system of heroes in One Punch Man has an error, what I
understood from the anime is that if someone reaches Top 1 in some X-class he
will have the option to get into the next class. but if that is true then if
this guy agreed, the guy who was in the Top 2 will be now in the Top 1, and he
will have the option to switch to the next class as well, and this thing will
happen until this X-class run out of heroes, but apparently, this thing didn't
happen in the anime.

so is this just some mistake that the author didn't notice or there is
something that I'm lacking?




That is a possibility but, in every class most of the Top 1 people will tend
to remain in that class in order to try and reign over that class. That is a B
class Rank 1 is most likely to flatter himself thinking that he has the
potential to be in A class Top 10 and will try to control those who rank
below.

If all of the Rank 1 people try to ascend to the next class the the give
scenario might be possible and there are no explanations from the author till
now.
