True. Utilization of NULLS has become a norm and therefore people learnt to leave with it. They have learnt to make subjective adjustments when they can not explain incoherent results (I can count how many statistician, accounting, and marketing people are called in datawarehouses to *validate* false counts subjectivity, I have encoutered). A a consequence, a part of subjectivity has been introduced back into validating accuracy of results.
