Welcome aboard In a nutshell you take a ceiling density that is allowed for an open rack while addressing all the variable and then add in-racks as required by 16.1.6. That includes open rack arrangements with in-racks and a lower ceiling density as long as 16.1.6 arrangement meets or exceeds the open rack in-rack arrangement. You also get the additional reduction due to in-rack sprinklers exceeding that required for open racks dictated by 16.2.1.3.4. This is hidden in section 16.2.1 (see below). I tried to have it moved to the 16.1.6 section but I guess that makes it too easy so the TC rejected it. That battle is not over.
16.2.1.3.5 For solid shelf rack storage, Table 16.2.1.3.2 shall be used to establish the density/area criteria and in-rack sprinklers shall be installed in accordance with 16.1.6.
