So it doesn't do what I want after all. :( Looks like @craigmaloney was right and Google have indeed done something to break it.
First come the Underreporter reviews which may bring up the Substantial Understatement Penalty (20-40% of what you failed to report gets levied as a further penalty against you) by itself if there are documents to match...or a full correspondence exam starts...or a field exam starts...or CI investigates.
