No change is shown to a boxer
moving up or down in sequence with other
fighters; i.e. just moved up one position
because of another fighter's loss or
inactivity. A ranking change is defined as
one whereby a boxer moves by virtue of a
significant win or a significant loss.
Boxers can win and not move up the rankings
if the win was not substantial to add a
significant number of points.
