Those settings seems spot on.
I'm trying to find RL doctrines for nuclear bombers during the early cold war in case of first/retaliatory strike, since we obviously lack actual combat situations, but from what I'm gathering it seems that it was generally acknowledged that their mission was likely going to be one-way, so I doubt they would've aborted for 10% damage and head back to their airbases which could had been destroyed by then, especially if already deep inside soviet territory and still able to reach their targets and deliver.
“I felt it would be a one-way trip,” says Clyde Ketcham. “Even if not shot down, after flying through all the radioactivity, I don’t think we would have lived very long, and on most missions, we had very little fuel left and really no friendly places to go after the last target. I think most crew members held down at the very bottom of their soul [the thought] that God wouldn’t let this happen. That’s how I kept my sanity.”

We can already set a plane to ignore bingo fuel, ignore aerial refuelling and press on, which borders on suicidal, we may as well have a doctrine option to ignore damage too.
