Most efficient training x Equal Training Time > Less efficient training x Equal Training Time.
It is possible that you can do the job inefficient with more work, but if you have a split second to finish the job you need to be very efficient in the constraint of the two second.
If a fight lasts more than two seconds you still need to be efficient within each split second of the confrontation, otherwise your chances to survive diminish as time passes.
Perhaps you can have someone "gain experience" over years of training, or program him in a short time of training as short as few days.

However while any individual in this world might be able to teach you something, there are only a limited amount of principles that should be distilled out of the methods of Hand to Hand Fighting.
One's brain's would never be able to process a mass of experience in a split second without drawing proper conclusion out of the experience.
To make the long story short, lets just say that history repeats itself and the number of bones and their shape in the human body have not been changed in at least in the last 100 years. The skeleton and bones dictate the range and direction of motion...
