REVISIONS HISTORY - Revisions: Between 9/4/2019 and 12/9/2019 the incorrect conversion of input equation was used. The equation did not contain parenthesis so the mathematical order of operations was performed incorrectly. To fix this, the raw values from the EDL data were put into an Excel spreadsheet along with the correct equation to provide the correct WL in feet below LSD.
