When I was still doing Sheet Metal repairer on Army Aircraft, all I needed was the starting point. You stated that you want 14 screws to hold the fairing, so find the point you want to start and walk the dividers 14 times. Adjust the distance to make it walk the pitch in or out until you have your 14 points and end up back at the point you started.
Yes, will also work, but a lot of trial and error involved. Whatever works, I say.
