from the diagram it looks like.
Long tree distance plus larger angle (ridgeline up to tree) exerts more pressure on ridgeline than straight to tree once the weight is in with sag etc?
cinch buckles, etc with mechanical advantage can set up more stress on ridgeline to start with.
so dont torque it down.
if the hammock is relatively level to tree, and not too tight, once we get in, the sag should not impose bad things. for longer distances, some increase in height on tree is required.
Have I got it backward? sorry too long since Geometry, physics, English class
I guess I don't think too much about it, if it looks about right, get in, just started using cinch buckles tho, so I can see where more stress can be applied than the lashings
