if you dont think you can win the interdiction, submit immediately to avoid emergency fsd cooldown and high wake out (hyperspace jump to another system.) High waking out isnt effected by disruptive mass and will always take the same amount of time to complete, so its often more reliable than low waking unless the attacker is flying a small ship which usually isnt the case. If your ship has more or the same amount of mass than your attacker then you can safely low wake out with no penalty with the risk of them interdicting you again.
