Xicount is an unofficial name given to someone who won all 8 of their heat games, hence becoming an octochamp, then went on to win the series. This means they won 11 out of a possible 11 games. The name is based on XI (the Roman numeral for 11), in the same way that Viscount is from VI (6). To become a grand slam winner, one must become a Xicount and then additionally win a Championship of Champions. The first ever Xicount was Darryl Francis, appearing in Series 6.
In Series 69, Dylan Taylor scored a total of 1319 points, higher than any xicount in any format at the time, but lost in the grand final to Callum Todd so did not become a xicount himself. A similar situation occurred more than five years later in Series 80 when Elliott Mellor scored a total of 1373 points but lost to Dinos Sfyris in the grand final.
