The decreases appear to be the same as a per game value for the ticket over 12 games, For example a Season ticket for $300 for 12 games means a $25 cost per game, and that is the amount of the discount the discount appears to be rounded up to the nearest $5 (Cronin 12 games = 24.17 per game but discount is $25). There appears to be one of two exceptions to this, (Cayless Adult is $15.83 per game but only a $15 discount, and Cayless Family is a $40 per game with a $45 discount).
