I'm not positive but 2 yrs ago that 20' restriction was in place under our applicable 2002 edition. Believe I just read something about the impending FNM changes that kept the restriction.

There is also a 20 ft maximum limit for distance from the top of storage to the roof sprinklers but I don't know if applies when there are in-rack sprinklers.
