I like the idea of an 0A freestyle competition best, but I can’t think of a scoring system that’s close enough to fair, besides a crowd vote or knowledgeable judges just scoring based on what they think it deserves, and even then, that has potential to lead to some unfairness.
Borrowing from kendama competitions could be cool. Like “Open”, where a list of tricks is posted ahead of time. One vs one battle. Rock, paper, scissors decides who goes first. That person draws a trick from a deck of cards(or random generator). The players take alternating turns attempting to land the trick, for 3 turns each. The player that lands the trick more than the other player gets 1 point. If they tie, then the round doesn’t count and they start a new round. With each new round, they alternate who picks the card, and a new trick is drawn. They keep going until one player reaches 3 points, and that player advances to the next round of the competition. It keeps going until you have first, second, and third place winners.
…or “World Cup”, where a large list of tricks is posted with scores assigned to each trick based on it’s difficulty. A player picks a specific number of tricks and the order they will do them in and submit it. During their performance they attempt this trick list in order and they are scored for each trick they land, and they earn bonus points for completing tricks consecutively. Players with the highest scores win first, second, and third place.
These types of competitions could potentially take a lot of time and effort. That may not be something anyone is willing to do because 0A is so small right now.
They don’t have to be held at an official competition though. They could be put together by anyone willing, either outside of a competition, at a yoyo club, at a park, online, etc.
Having these types of competitions could be incentive for players of other styles to pick up a responsive throw and join the fun, or be an incentive for more players or new players to pick up 0A in general, and lead to the growth of 0A, and lead to greater interest and desired participation in 0A competitions. Who knows, maybe “if we build it, they will come.”
