No minimum and no maximum. If there are 30 events in a day, you only got to choose the ones I write posts about. So, there's no question of how many or how many not! There are actually 42 Sports in total and for each sport before it begins, there shall be a post about prediction for 🥇 🥈 and 🥉. So, there should be 42 predictions posts.

For example, Football will commence on July 24 and has 2 events, one 'Men's Football' and Two 'Women's Football'. So, for this sport a post will appear at least 24 hours before the sports actually commences. There, every participant has to just predict the Gold 🥇 silver 🥈 and bronze 🥉 winner for the whole event.
