Correct re: the 13 part. But my post is 100% accurate in that West Plains would earn a higher district rating by beating a class one team by 13 points which finishes with a 1-8 record than if they beat class four Hillcrest by 100, assuming Hillcrest finishes 0-9.
In both cases WP gets the +13, but their Strength of Schedule factor is better by beating a 1-8 team than beating an 0-9 team, assuming both are in their same class or lower.
The thread was initially about getting penalized or not for playing down. My point is you don't get penalized per say, but what is important besides winning, and margin of victory (maximum +13), is the overall record of your opponents besides what they did against you.
West Plains beats Hillcrest by 13+ and Hillcrest finishes 0-9.
Carl Junction beats lowly East Newton by 13+ and the Newt finishes 1-8, this gives CJ a slightly better district rating than WP in these specific games only. Then of course the other 8 games come into play.
