Instead of this rubric I would look into the points difference at the end of each match and work on that. Otherwise it’s way too heavily weighted.

For example, imagine a final where the winner gets decided by a half court three point buzzer beater. That game was effectively a tie with luck being the deciding factor. But now the winner has double the points of the second place.

This causes a huge leapfrog effect that pushes the champions higher and higher.
