It's not really difficult to be accurate when you update your datas(and sometimes not adjust at all but people forget), from people who are really accurate and dont guess.

Why do you ignore that the rest of the data is usually within 10% of the NPD before the adjustments

Because a good part of the data are not, so you never know what are guesses invented numbers and what are estimations. So useless
