Evaluation Result: ********** **********

The 'Total Possible' column (C) represents the number of trees that potentially have that element (A). Non-sawtimber trees do not have the elements that pertain only to sawtimber trees (for example, sawtimber height). In/out trees are only counted for plot or point cruises.

A measurement is incorrect if it is not within the specified tolerance (B) of the same measurement made by the check cruiser. The number incorrect (D) is multiplied by an error weight (E) to get the total error (F). The total error is compared to the total possible to get an accuracy score (G).

To pass this check, each element checked must have an accuracy score of at least 80 percent and the overall accuracy score must be at least 85 percent. In addition, the calculated volumes must be within the specified tolerance.
