The 'keep the dot on the target' method will always work. As others have said, it may not be the most efficient interception method but you'll get there in the end (even if the target speed vector is changing)
as long as the intercepting aircraft has the performance and manoeuvrability to keep the dot there.
Do me a favor.. next time you shoot an approach, stick a piece of gum on the windshield outside the marker corresponding to the touchdown zone markers on the runway of intended landing. Let me know where the piece of gum ends up on a 1/4 mile final with respect to the touchdown zone. Make a video.
