Way back in the day, in Starfire, (the board game that the SE-series is modelled on), there were regular PD systems, that were highly efficient against missiles, and less so against fighters. And then there were also "improved point-defense" systems, that were highly efficient against fighters, and less so against missiles.

Speaking of which I couldn’t model this since you can’t use two separate to-hit formulas. But I did find a good middle ground.
