I believe that what you've described, which is what I had as Option 6, is the club's standard approach to this scenario normally. However these aren't normal circumstances and although we were planning to have a seasoncard amnesty anyway, the club's primary concern in these circumstances is to have accurate contact details for all ticketholders. But if all you'd be getting is 1,000 points if you're curently using a ticket that has 20k points on it, the chances are you're not going to do that, thereby impacting the club's need to have that current data.
So we need to maximise the conversion rate, which is what the club wants and therefore might involve having to give people some incentive to do that. But they might equally well decide to enforce the normal rule of 1,000 points only, so as not to upset others who have gone down that route and take the risk that people choose not to transfer but the people take the risk of not attending a game for the foreseeable future. They will have to eventually decide, hopefully with input from us, what suits their needs best, rather than what might upset someone on Bluemoon.
There is no simple answer to this that will suit everyone and I think most people understand this.
