9 games (titles) of qualifying, each title has three challenges that consists of playing up to 5 balls in order to achieve that challenge. You must attempt each challenge individually, so you can't play one game and get multiple challenges. Thus, everyone is guaranteed 9 x 3 = 27 games (multiplied by 1/3 because you can finish on one ball) = 9 games TGP for qualifying

Semi finals is top 8 players with the lowest combined time across all challenges across all games. Two groups of four, with four games with three challenges per game = 4 x 3 x 2 x (1/3) = 8 TGP
4-2-1-0 scoring per game (add up the time in all 3 challenges in a game, compare that to each other player on that game to determine placement)
Finals same thing = 8 TGP
total = 9 + 8 + 8 = 25 TGP = 100%
