I think the consensus is that the extended norms are useful and can't hurt, and some people here also reported that their testers simply didn't know about them. Can you forward Technical Report # 7 to your tester and have her include the extended score(s), maybe reissuing the report? It will probably cost a little money unless you were charged a flat fee, but I personally think it would be worth it.
