HMG Square tarp : How to achieve full coverage?

I’ve opted for using the tetrahedral configuration to get complete coverage  with an 8.5 ft square tarp, set up as seen below. Therefore, for about 1 pound including stakes I can simulate most of the features expected of a tent- with much more versatility and durable, complete waterproof coverage with no fabric stretching ( as cuben fiber does not absorb water).

There are also some significant potential advantages- among them, being able to cook in the shelter under proper conditions, much more interior space than any tent of anywhere near the weight, and 360 degree viewing of the surroundings depending on the height of the pitch, and ability to hang the tarp from some exterior object, such as a tree limb, to further increase interior space and make adjustment of pitch very easy. The guylines can be placed and adjusted from inside the tarp.

As usual with this 8.5 foot square tarp, there is versatility as to how much ventilation vs weatherproofing can be dialed in depending on how closely the tarp is pitched to the ground. This means that condensation can be easily minimized.

I use up to 14 stakes ,in order to maximize coverage over the ground and stability of the system. Therefore, no additional stakes needed vs the usual types of setups such as flying diamond or A-frame variants.

It’s easy to employ a biv sack inside if complete insect protection is desired. I’d use either the larger REI MInimalist or the very light, ~ 7 oz Titanium Goat Ptarmigan sack.
