I haven’t tried out your Trapezoid Diagonal formula yet, but will once I get my replacement tripod. When I first started measuring tree heights several years ago, the ease of use of your formuli coupled with additional directions from Will Blozan and Ed Frank made the learning curve short. Your trunk volume spreadsheets are equally intuitive. My preference is to have the equations hidden inside the cells, but included somewhere below or to the side of the columns.

Thanks for your work,
