They started off with a poor basic design, and spent several years trying to make it work. I doubt the guides were really happy with it at the end, but management probably got tired of waiting. Ah well, the guides got some fun trips out of it.
It's a 2-man tent which weighs 5.17 kg (11.4 lb). Light-weight, eh? And it looks no different from any other heavy geodesic tent on the market. That's not how they build extreme weather tents in New Zealand or Northern Europe: I wonder why (=sarcasm). And it takes several guys to pitch it in bad weather. Sheesh.
OK, tent poles.
Trying to do useful tent pole calculations is almost impossible. The reason is not to do with the pole; it's because the main reinforcing mechanism keeping the pole straight is the fabric around the pole - assuming the poles are sleeved in the fly. OK, on a pop-up tent (or some geodesics) where the fly is thrown over the top the fabric does not help very much - which is why pop-ups collapse so easily and geodesics are so heavy. Bad initial design. Sleeving is essential.
Why can't you model the effect of the fabric? Because the loads depend totally on exactly (and I mean exactly) how the tent is pitched, how strong the wind is, how much stretch there is in the fabric, where the guy ropes are and how much tension they have, whether the poles can slide under the fabric (as in pop-ups), ...
Wha does matter is to calculate the minimum bend radius the material can handle, and to make sure the actual bend radius (at the top of the arch) has a big safety margin over that (for storms etc). You can put a pre-bend into the aluminium poles, and that helps enormously, if done correctly. Been there, done that (both the right way and the wrong way). And sleeve the poles in the fly, don't throw the fly over them.
