Don't see many complaints about last nights structure because...
... the 200 people who didn't like this structure aren't playing any more?
you need to check your maths Jon. of the 200 that have dropped, around half dropped after the first week - so perhaps that's because they didn't like wk1 structure.
Almost everybody who registers does so on the Sunday (and most of those who don't register on the Saturday)
i.e. It was after the week 2 structure was announced that it had the drop off.
tbh I think most of the week 1 drop off was just natural wastage but some of the week 2 drop was dis satisfaction with the structure - primarily I just wanted to point out that analysing the figures is more complex than just looking at one factor.
