Looking for love in all the wrong places again. SS rules are for SS and ESFR rules are for ESFR, and n'er the twain shall meet. Or at least where the do use the proper separation to keep them apart. It's age 272 in the 2013 edition of the handbook. Your milage may differ using the 2007 model (mine's at home so I can't check it), but even if not on 272, I'm putting money on it saying the same thing.
