>It's not a combat drill
Matter of fact it is presented as a combat drill, given that the origin of it is a shooting of a man in combat, and the purpose of it is utilitarian 'elimination of a threat' based on appraisal of his up/down state, not 'score enough points' or 'improve marksmanship'.
BUT EVEN IF you assume that you're training it for sports purposes, which is its own can of worms, training this drill specifically is inefficient.
Training Mozambique
>Land two shots in A+C box, any combination
>Transition to a fixed target upward, land one shot in A+B box, any combination
2 out of 3 shots you'll fire are on an 'easy' target, then you follow up with a specific transition upward towards 'hard' target. The result is kata-like maneuver that is extremely rigid, and forces you to spend 2 out of 3 rounds on a 'satisfactory' result of chest A+C, which is no help in hitting a much harder target of head A+B.
Training splits on 6" bullseye or A-box only.
>Land two shots in effective A+B head box/A chest box/6" bullseye, any combination
>Transition to the second target of the same size, land same two shots
>Change target positions and elevations to challenge your transition speed and accuracy
4 out of 4 shots you fire are on a smaller, head-esque target, and then a random transition. The scoring only applies to what would be equivalent to A-chest and A+B head on mozambique, calling for a tighter group on the splits, AND calling for a split on the small part as well, for 4 shots total.
If you train only bullseye, you improve yourself generally as a shooter AND get better at Mozambique Drill simultaneously.
