Re: flow, or technique
IMHO, this is the problem with individual learning strategies and group instruction.
Sequentially, some people learn better with the big-picture (flow) first and then adding the smaller-picture (technical proficiency). Its like a jig-saw puzzle where the most important piece is the picture on the cover.
Sequentially, other people learn better from the parts to the whole.
Often the style/school follow what learning strategy/sequence the founder/instructor found worked for them personally.
Many times people can only do one and not the other.
IMHO, sequencing implies eventually doing both.
