J/30 Class Association Forums J/30 Forum Racing Tools and Techniques PHRF rating

I have decided to play the PHRF game and have made purchases and adjusments as such

My original PHRF was 144(base -3(spin pole) -6(163 genoa) = 135
This season I have a new power head main (6 sec penalty) and plan to use it with the 150 genoa (if this works, then eventually get a new 155%)

Would I be correct to assume my new PHRF will be the same?
144(base) -3(spin pole) -6(ph main) -0(genoa) = 135
