There are bombers running from fighters as well.
Which I don't really have problem with, even though it may suck on a personal level when I can't reach that high Mossies and B-29s, or Arados diving away.
Using your plane's strengths is quite something different than bailing just to deny someone a kill.
That's why I'm all for matching rpoxy kill range with icon display range. "Oh, it's a hostile 190! I better bail..."
But of course that would not deter the "bailers for war efficiency" in any way.
