"The thing no one ever seems to mentions about pyramids is the bottom mid-point tie outs. If you make the base square, these are always up in the air."
I had tieouts on the middle of each side of my puramid.
During a windy period some of the stakes for these middle tieouts pulled out.
The thing is, at the corners the tent pulls more sideways on the stakes and has a constant pull.
On the middle, it pulls up more on the stakes, and it flaps around so sometimes there's no force on the stake, then it really pulls on it. It would help to drive in the stake more at an angle, than verticle.
But, duhhh, if the middle stakes pull out and the tent stays erect, then I guess you don't need those stakes.
It would be easy enough to put the loops in, and wouldn't add much weight, and then you could use them or not with experience.
I don't think you need to put cat curves in the middle. The silnylon stretches so the cat curves on the ridges will result in it being taut in the middle also.
Yeah, the middle points are up in the air a little, but that's fine because it lets in a little air to minimize condensation.
