Can I use Section VIII Div I Appendix 1-10 for Hillside Calculations?

Can I use Section VIII Div I Appendix 1-10 for Hillside Calculations?

Can I use Section VIII Div I Appendix 1-10 for Hillside Calculations?

(OP)
I use hillside calculations per the non-mandatory appendix L 7.7 for carbon steel sch-40 pipe nozzles in carbon steel shells with temperature <400°F and 125 PSI MAWP. The 2010 version of section VIII Div I allows reinforcement per appendix 1-10. There is a provision in these calculations to input a radius of the nozzle along the long chord "Rnc" however it is illustrated along the longitudinal axis of the vessel. I would like to apply a 0.5 "F" factor and use this long chord dimension circumferentially if this is acceptable. None of the formulas in appendix 1-10 actually call for the "F" factor although "Fa and Fp" are listed in the nomenclature section of the appendix. The longitudinal axis calculations usually drive the reinforcement required but if I choose to provide normal to the axis calculations using appendix 1-10 then for consistency sake I would prefer to use the same style calculations for the hillside.  
Any help on this subject would be greatly appreciated.
