This is very true, the whole thing is a BFM trainer.
I would say just go for it, you don’t have to “fly” through it (pun intended) you don’t have to be perfect straight away and by the end you’ll be a better sim pilot for doing it, it’ll also improve your flying in the B model indirectly.
So what if you have to fly a few missions a couple of times as long as you’re learning something and enjoying it, that’s the whole point in the end.
I judge success by coming away and having learned something and also having fun, doesn’t even matter if I made it to the end of the mission or not, I will next time. But that’s me and we’re all different.
