Calculation by itself doesn't make it inaccurate it's the near field to distance relation which makes it invalid.

But that does not necessarily make them inaccurate. They could be accurate by luck, we need more data in order to support either position. Does anyone have contact info for the two authors?

The table, Table 2, does not seem to have a reference of footnote describing the source of the data. Does anyone know the source of that data? Is the data measured or calculated?
