"Is it more "correct" to maintain a uniform curriculem vs. diving in a much smaller set of techniques that are tailored for personal goals."
Another thought-provoking question!
My personal opinion is that the latter would tend to help explain why there is so much variation between people that trained in the SAME system and even under the SAME teacher. Essentially that back in the day more focus was placed on the "tailored for personal goals" than the "uniform curriculem" part.
You could probably add "tailored for individual strengths and weaknesses" to the list as well. IMO.
