In any comp it would be a big call to walk back 5 games to make a decision on standings. I get the logic but it would be harsh to ask teams to forget recent results, at that point you should be considering nullifying the whole thing and trying again next season.If they don't get the competition completed I would think they would take the table as it was at the end of Round 11 after everyone had played each other once as this gives the fairest picture overall. Unfortunately we were 6th at the time and would miss promotion. If they took it as at Round 16 there would be grounds to be considered unfair - especially as we played 3 of the 4 bottom teams in the first 4 rounds of the comp.
Can't say I have much hope for the grassroots season. Might get another 3-4 rounds in tops to minimise the refund CCF would have to offer.
