It seems that we are about the same age and obviously got our offer of PA at the same time. My recollection is slightly different, yes one needed 5 years of service to be allowed to transfer to the scheme and that was , I believe, due to the 5 years being a minimum time to achieve an enhanced pension (ie PAS) under the 75 scheme. I don't remember a ban on PVR within that timescale. If one did PVR with less than 5 years PA then one simply got a SA pension. Of course nowadays those assimilated who do leave before 5 years PA have no SATOS to fall back on.
For those PA on 05 scheme I would have thought that the EDP was based on the final salary(best 365 days in the last 3 years) like everyone else on that scheme.
