I'm trying to construct a view that correctly compiles standings for a youth rugby (rugby football) league.
Our Stats keeper, who has been helping me beta test everything, has discovered an anomaly with respect to how "BONUS POINTS" are being awarded by the logic of the View [MasterStandings]. It appears that a BONUS POINT is being awarded to a WINNING team for a score within seven (7) points or less of the score of the losing team. This is incorrect. The rational of the "losing" BONUS POINT is to encourage a team to keep playing hard even though the players may realize they are unlikely to win the game. Per league rules, a winning team is NOT awarded a "losing" BONUS POINT.
The league rules for awarding BONUS POINTS are:
(i) A team is awarded one (1) BONUS POINT for scoring four (4) or more "tries" in a game  regardless of winning or losing the game; (ii) A team is awarded one (1) "losing" BONUS POINT for losing by seven (7) or fewer points in a game. The winning team is NOT entitled to a losing BONUS POINT.
Thus a winning team may only be awarded one (1) BONUS POINT if it scores four (4) or more "tries"; never two BONUS POINTS.
However, a losing team can be awarded one (1) BONUS POINT for scoring four (4) or more tries and/or one (1) "losing" BONUS POINT for losing by seven (7) or fewer points in a game. Thus it is possible for a losing team to be awarded two (2) BONUS POINTS in a game.
I have been scratching my head as to how to resolve this anomaly. I'm hoping someone on the Forum can solve this problem or at least point me in the right direction.
DDLs for the two primary Tables, dbo.MatchSchedule and dbo.MatchResults, the View dbo.ResultsMaster, and the problematic View dbo.MasterStandings are appended below.
Many thanks!
Here are the DDLs.
