My first response to your NASA post, at 2.16 yesterday, was civil. Not only that, it addressed your post quite closely. Since then I've received a tirade of insults and defensiveness from you. You have a track record of demonstrating insecurity and defensiveness when you are pressed on some of the statements you make. You have my view, stated clearly, on the limited usefulness of return-period statistics. You attacked me because I challenged your appeal to NASA authority. Too bad. Show some spine, man, and take on the argument if you have enough conviction.
