Even though you have given her the documantation, in the NFPA 220-1999 and NFPA 5000 it directly states that due to construction differences from locality to locality, the AHJ has the final word in deciding the final wall rating. I've been in a discussion with an inspector about a wall I considered to have a 15 minute fire rating, and he did not. In the end, I ahd to back down because of the way the wording is, it directly gives the AHJ the final decision
