This is what Homer called the "chain" of Positions and Motions.
The Twelve Sections of 8-O could also be called Geometry in Motion, asource of recent confusion on the site.
The Twelve Sections concept gives you a means of examining your Strokein a series of twelve "air tight" compartments (ranging fromPreliminary Address to the Finish). Improvement in any one compartment bringsultimate improvement to the whole. [Yoda's Warning: If your recentimprovement just ripped-off a major band-aid, then the improvement could behazardous to your short-term results.]
In short, use each of these sections per 12-3-O to monitor "what positionyour position is in." In other words, use them to apply precision G.O.L.F.alignments to the current state of your Total Motion (12-5 #1, #2, and #3). Per12-O, "Precision in -- precision out."
