There is a key-bind to use to see what ship is interdicting you - I always check because depending on the ship, you can choose the right scenario.
If I were in my MkIII, I'd pretty much submit (if the interdiction was taking too long), chaff and boost, then wake out of there.
The Warthog 4 way hat has Next Hostile/Prev Hostile/Next Contact/Prev Contact and during my 1st interdiction (which I won BTW) I tried using Next Hostile but got no target. Maybe there's confusion on my part but maybe only Highest Threat works while being interdicted since the interdicter isn't hostile until they fire on you?
During my 2nd interdiction I lost and was spinning all over the place so it took me a moment to get my bearings. Within a few seconds a thermal attack took out my shields. I don't have chaff normally but I boosted away while waiting for my FSD to cooldown, I turned and made a run at the Anaconda hoping that he couldn't outmaneuver me and that I'd have time to get away. I took just 2 or 3 hits and my hull was falling fast. He turned around very quickly just as I passed him and I hit the rear of his hull with only 19% left, that was the end of that engagement.
With enemies near my own level I like to submit and attack. With something like this deadly Anaconda I should have hi-waked but I didn't have time to get far enough away while the FSD cooled down. Even then I would have run into the same NPC the next time I tried to enter the system. I didn't mention this earlier but while making these deliveries I got a message that if I took out the attacker I would get payed a bounty, so this wasn't a random NPC.
The best choice would be to not take on a trading mission 3 levels above me where the hostile attacker might be 6 levels above me. I'm currently Mostly Harmless but only due to wiping my save a few times over the years, I'll not claim to be any kind of expert at ED but I've been playing since v1.5. I want to get better but I'm just not the type to submit and run, those that attack must pay! [mad]
