During a 13 TC meeting on just this topic, the FM guy (at that time -
Joe Hankins) stated that FM had tested mixed commodities and you
definitely had to assign the actual height of storage for the higher
hazard even when the upper portions were a lower hazard. The fire was
far worse than a one would see for the higher hazard at its lower
height.
The idea by Chris to segregate with in-rack sprinklers (insert at
EVERY flue) is a defendable equivalency approach.

Right now I am leaning towards the FM guidelines they do have some
options for getting it done without in-racks.
