I understand that this is due to the National Women's KO Cup round, rather that put the reminder rounds all back a week that round will now be played at the end of the season, so at the moment some clubs have yet to play one another so will face each other twice in the final three weeks of the league. In Coastal's case they have their two bye's in the final three rounds.
That's better than the 2 games per weekend at end of season that Coastal have played due to Cup runs in the past.
That last happened in 2012, only 12 games this season.
