The AS-BUCKED (Scenario 1) solution achieved 90.4 percent of the optimal $2,466 under the board foot basis.
It should be noted that the BF/CF ratio calculated by dividing the total board foot volume by the total cubic foot volume for this scenario is 3.63.
Scenario 6 (20-ft lengths only) had the lowest board foot volume of any scenario, likely because for 5-, 6-, and 7-inch diameters, the 20-foot length sits in the middle of, or just before, a board foot step breakpoint (NLRAG 1995).
TREEVAL may be the more appropriate tool to address mill-length log values if the conversion from board foot prices does not reflect true market values for logs on a cubic foot basis.
