Pk of interception is higher when missile is approaching re-entry. The azimuthal accuracy from Radars is weaker compared to range accuracy. And launch a ABM that later requires wide correction makes it infeasible. So once radar sensor fusion is able to arrive at a solution that predicts missile in time space such that it fits into the relatively small kill box envelop (as determined at the moment when ABM is launched), then one can launch the interceptor.
Hopefully with above one can see that mid course interception may not be most effective. Unless there is a grid of radars on the way with high accuracy and the trajectory can be more accurately determined before the missile reaches Apogee. As Indian sensors improve and grid becomes denser, mid-course interception will be closer to reality.
