A fan phoned the club about it, I saw on social media. It works over a three year period and the club have taken off points that are outside of that period. Its happened to all fans that it applies to.
This is wrong., sorry Atomic.
It was 500 points for a season ticket, 10 points per home cup game, and 5 points per away game for the previous 3 seasons. I was around 1800 for the 2019-22 seasons.
It would have been moving to 2020-2023 seasons but the points would still be true.
It looks like they have totally reset the values of tickets bought
Either way, just communicate with the fans beforehand.
