Well, if you must use a live auditor, and a meter, I suppose it's OK.
Joking aside, I've heard this works out quite well if you insist on that regular stuff. It's obviously not as good as face-to-face auditing in the same room, but that is only in theoretical terms, balanced against the advantages of being audited at home instead of maybe several thousand miles away from home with the added expense and inconvenience and time off work etc.
Balance. Now there's something I've never had in my life. Especially not in the church. Thanks Paul.
