Welcome to the forum Paul. We have a long-running thread about the Ross system which a large number of well-informed people are subscribed to. If you post your question in there it will certainly get answered and probably quite quickly.
I'll look up the thread just now - in the meantime I've closed this one to avoid duplication.
