IDK about FM. UFC is clear to me, no you can't use small room - area/density only, and no the calcs are not per FM. There are 5 things you pull from FM and only these 5 things, density, design area, hose stream allowance, duration and minimum k-factor. And really these only apply to things defined as HC1-3. For example HPS would follow NFPA 13.

The UFC is confusing as the installation goes by 13 and the calcs go by FM standards.....
