As explained the estimator is more for cg shift as modifications are made. When I created it I think I both scaled the middle of the tank from a brochure as well as measured it on the boat.
Being an ex PW engineer also, I over-geeked this myself. I modeled my entire 23 Sceptre in 3D CAD and checked the computed CG against fuel tank location - the calculated CG is within 1" of the center of the tank so that is consistent with the legends and folklore. I was stunned but it really makes it a lot easier to understand the effects of changes I make.
