Re: I'm not certain...
I'm not certain about the reasoning
why those points were removed from the system. But from my long years of paying attention to how this works, I can tell you that those points have not
always been part of the system. Not even close. They were added in the 2013-14 classification cycle, so they had only been part of the system for two seasons.
Now, "bonus points" have always been part of the system (as far as I know). Those reward you for playing up IF the higher-division team finishes with a good record. Those points aren't added till the end of the season in the final ratings. Many times, a team that was hanging around 5th or 6th would suddenly jump into the playoffs in the last week because they got a lot of bonus points at the end.
So if Bishop Sullivan finishes 9-1 (or 8-2 or 7-3), BSH will still get some points at the end of the year. They won't get 5 like they used to, but they will get some. But if Bishop Sullivan finished 1-9 with their only win being against BSH, BSH would not get any points for that loss.
The VISAA has launched a shiny new web site since I last looked, and they have the points system outlined on the "Sport Guidelines" page under Football.
