I can't vouch for them personally, but last year we had 2 people camped near us that had a similar, if not identical tent. They seemed to fair well using rebar. That being said, I don't think we had anything near 75mph winds in 2013.

Myself, and six other Arizonans in my group were able to get tickets! We're still crossing our fingers for some others in our group. Good luck to everyone!!!
