I don't use curves. I don't fly FA Off all the time. To me it's nowhere near realistic to do that. I promise you the Astronauts who flew the shuttle didn't, especially when docking with the ISS. They used computer control with fly-by-wire. Telling the computer what they wanted done and letting the computer do it for them. Much more accurate that way, safer, and prevented the need for major repairs. Only time I use FA Off is while turning in combat, lining up for outposts, and lining up and going through the mail slot. Auto-stabilization is there for a reason. I use it when I need it and turn it off when it's disadvantageous. Just like a real space pilot would do. And no, I don't use yaw to line up to outposts. I use my lateral thrusters and then FA Off and a tiny burn of my top thruster and drift down to the pad.
