Thank you for the nice report on the great Sycamore in West Virginia. In your report you said you took four measurements from three locations, How did you settle on 117.4 height as the best of the four measurements? Here in Kentucky I also use a laser rangefinder (Bushnell Legend 1200) and scientific calculator to measure various trees. Selecting the best height measurement when I take multiple measurements is sometimes a question when I do my measurements. Do you have any suggestions?
