Been playing since 1.2 and still learning to use FA off in various interesting ways. Once FA off became intuitive I started experimenting on advanced maneuvers.
Countering Jousts. Time my boost FA off flip so the NPC is facing me as it passes. Keep FA off so you slide backwards a bit. Boost. Much of th boost is bled out by the backward momentum. This so you don't overshoot the NPC while trying to stay on its 6. Use maneuver thrusters to further bleed speed as necessary
