So just a clarification, when you say:
"Awarding prizes for the Leagues: Up to 150 people who complete the Gold League will win a t-shirt." and "25% of the people entered into each raffle will be selected."
If the league only had 35 qualified winners, then you'll just get 25% of them(9 people). Is that correct? And the up to 150 limit is only for let's say there were 700 qualified people, only 150 will be awarded and not 175?
