With 23 teams in Champ/C1 it would mean that you cant play everyone H & A, so for example you dont play 7 teams at all , which when designed at start of first season it could be seeded so bottom of C1 dont play top Champ teams, Fixtures done by position numbers not team names. so works easy every season.
Not playing 7 teams means you would still play other 15 teams H & A like we used too pre SL start.1995
This current season started on 23/Feb. and ends on 7/Sept prior to play offs
During this we will only have 18 matches [9 home games] - during this period we will have had 11 blank weeks, ELEVEN blank weeks THEREFORE almost 3 months of blank weeks - which means we could have played 15 teams [30 games] in this same timespan,
This is Probably to difficult for RFL to organize - but somebody clever could sort the fixtures out.
