In most cases, the grand prize will be determined at 15% for a 20 team league. 7.5% for a 40 team competition, and 30% for a 10 team tournament.
However, consideration will need to be placed here. In the event where 1 option in the league receives overwhelming take-up rates. This is because, if a 'favorited' team contributes more than 15% of the sales during the event presale, and the champion having only 15% of the prize pool allocated, the 'favorited' team option will take a loss at the end of the event, even if the 'favorited team' ends up being the champion in the end.
