I assume that you mean the “Atmospheric Pressure, Selected Heights” quotation.
Simple calculations do not always take into consideration all the variables that are present in the particular instance.

For example if the barometric formula is used for the higher atmosphere without taking the temperature into consideration, then the results will be in error.

These pressures are considerably below those predicted by the barometric formula, which can be used to calculate variations in barometric pressure with height near the earth.
