I said earlier in the thread that 2 years has been the standard in other schemes I have been in in the past. It's one that always gets some people upset though because they don't understand what is being said and think they will lose all their points and are going to have to start from scratch again which obviously isn't the case. It's about looking after those who attend most often at any given point in time and not allowing someone who attended loads 5 years ago to have a legacy entitlement even if they stop attending in the present. If you attended 5 years ago and still attend now then you stay at the top of the list. Simple really.
