Current set score dropped from or padded into the set list · case 02
An in-progress set is missing from the scoreboard, or a phantom "0-0" set appears after a set ends.
Case contract
games is a string of game winners (A/B); best_of is 3 or 5. A set is won by the first player to 6 games with a lead of two, or at 7 games (7-5, or 7-6 after the tiebreak game played at 6-6). The match ends when a player has won best_of // 2 + 1 sets; later games are ignored. Return [set scores as "a-b" strings in A-B order, match winner or None]; an unfinished set with at least one game is appended as its current score.
