That’s unfortunately what the algorithm gives when it doesn’t know very much about you: bottom of the barrel slop. I’m the opposite and stay logged in, but I’m also diligent about removing items from my watchlist if I didn’t like them, or if I see they’re skewing the algorithm.

No it’s not. Nothing is invincible. Doesn’t matter how much armour you put on a helicopter or a jet, there will be weak spots (rotors, intakes, etc).
Loosing a single helicopter in a fluke is not a bad look. If it happens frequently that’s a different story.
