If the fins are forward of the BT end by x, do you calculate that aft area as a "zero change" conical transition?

But the Barrowman approach only gives an estimate, and I doubt it was ever intended to address every peculiar design that we could think up.
I have also always wondered at the way fin effectiveness is analyzed. Barrowman gives absolutely no credit for fins with a good airfoil section, and treats all fins as though they are flat plates with sharp edges. Theoretically, well-airfoiled fins would be *much* more effective than flat plates.
