Dan; that is the DWT spread sheet; that i copied and extended in the link above so you could compare outputs of same loads at varying angles to show the patterns of loading.
We wouldn't take the computer to the field i think; just rules of thumb/ familiarities from the study at desk. For me that was cross comparing of what happened when/ at what change.
These do assume the line is not slanted; jsut showing the leveraging of bend/assuming support hitches at same height. In reality we would have the bend angle of the line and how much the line was slanted/how much it was not inline with the downward force flow of gravity. Inline would be nominal/minimal/base loading. Also, on slanted line, the friction/grab on the line would matter. Zer0 friction on inline with single support would be Zer0 loading(?); adding friction/grab and or changing slant and/or support count would change things along with bend(?).
