Cursory glance got me questioning a few (but suspect there are definitely some errors), for example:
U21s - just 5 teams, 2 from Universities
18 div 1 boys (clubs) looks incredibly weak - 6 teams: Amberley, Mid Canty, Christs second X1, Cashmere 18A and 17B, FC20LMNOP
18 girls - 2 x Coastal teams? surely not.
17 boys div 1 - 2 x coastal teams again? oh dear.
16 girls - disappeared completely?
and that's just for starters.
