I'd venture to guess that the utopia/lab conditions for EMI/RFI are probably on the conservative side if anything. Unless you live under a broadcast tower.Utopia/lab conditions don't guarantee normal expected operation at home which is IMHO what really counts.
I would also argue that lab testing separates the wheat from the chaff.
