The Kashdan tiebreak is a tiebreak which uses a pattern that praises playing above not playing. The pattern is to award 4 points for a win, 2 for a draw, 1 for a loss and 0 for not playing/bye. In Pairtwo however, the calculated pattern seems incorrect and seems to be implemented as 3-1-0 (same like football/soccer).

After a search for answers this appears to a wrong implementation as the USCF handbook does not mention this way of calculating.

4E7. Kashdan.

This system rewards aggressive play by scoring 4 tiebreak points for a win, 2 for a draw, 1 for a loss, and 0 for an unplayed game. Note that if players with no unplayed games tie, the one with fewer draws will come out ahead.

To avoid issues I decided to hold the official calculation and write this guide. The 3-1-0 scoring is available as Tiebreak::SoccerKashdan
