I take your point about PD opening up just before they can do normal damage but that can be managed somewhat by say phasing in the damage a little earlier:

Instead, what you can do is set a no-fire zone.

Weapon Damage At Rng := 35 35 35 35 35 35 35 35 0 0 0 0 0 0 0 0 0 0 0 0 1

Now the only problem occurs in fleet battles, where you have many missiles at widely varying ranges from your ship. One of the missiles going for your distant wingman might trigger your PD just before the missiles locked on you hit.
