     Velocity is a vector so it depends which way the target moves. Worse, the   
   target is now moving so the missile has to integrate its movement continuously   
   to hit it, successive-approximation-wise.   
      
     Generally I'd say no though. The farther the missile is from the target, the   
   larger the eventual effect of small lateral deltavee changes.
