Spot on. One of the main discussions we had with the club when talking about potential reform of the points system was the impact moving to a 5-year rolling system would have on people currently at the top of the ladder.
Personally I'd prefer to do that on a gradual basis, so things like dividing your current points by 100, so you always retained a slight advantage, or a system whereby we gradually transitioned to a new system so that higher points holders kept their position, but maybe by knocking off 20% a year over 5 years, or something like that.
As has been said previously, the club are interested in maximising attendance so. points would be given for actually attending league and cup games rathe4 than signing up for the schemes.
Be interested to hear any other sensible suggestions.
