I think what Bob is asking is like me asking when my First Aid certificate expires...I can renew my First Aid certificate within 30 days of it expiring by doing a one day renewal course. If it is 31+ days since my certificate expired I need to do the full 3 day First Aid course. The criteria as to renew or new here is set by the training organization.
Getting back to the question, I think read it as "does Augusta require you to do a factory initial course again if it is 5 years since your initial initial without having done a refresher course in that time, or, once you have done an initial you only ever need do a refresher".
