You got it right, the other thing that could be noted is something with a 11ft ridge, as the Speer winter tarp is 11ft, the OES Deluxe is 130" so that equates to what something like 10'8" or so, and the Warbonnet Mambajamba and Superfly are both a 11ft ridge! If you were to plug this in it might change the view on the amount of coverage? Also there are some Diamond/Asym tarps now with a 11' ridge or so, so this might change the amount of side coverage as the tarp can be closer to the suspension!?
