We've scene at least two projects killed because the AHJ refused to grant a reduction from the fire code tables. One of those was because of a standing policy against traduction in fire flow universally and the other hinged on 13R systems. In that case, the developer had received such bad advice that they were under the very sincerely held impression that the cost of 13 systems would make their crappy little apartments too expensive to build

And I love when the specifying engineers don't research the local amendments. One large jurisdiction here does not allow a reduction in site fire flow for 13R systems, and only a 50% reduction for 13 systems. I'm the bad guy when we have to tell the developer that they have potential problems because of local requirements. It's getting better but still happens.

There are more than a half dozen methods that are used. Once you find the method to be used, you will use the calculation methodology prescribed within. Of the different methods, the results can vary dramatically. Call the AHJ. If they say they don't know and don't' care, Appendix B of the IFC is the simplest method. But other methods may be more favorable from a water supply standpoint depending on the type of facility you have. Some don't care if the facility is sprinklered or not, others allow a reduction in fire flow if the bldg. is sprinklered. Craig L.
