The target line can and must be rotated to be in line with your intended target. It is moveable.
The term Target Line always refers to the Flight Line, the straightaway direction of Aim. The term Flight Path refers to the total ball behavior (including any curve) on its way to the Target (7-3). The Target Line is dictated by circumstance and is immoveable.
Stance Line and Plane Line are moveable and can be aligned (in relation to the fixed Target Line) to produce any one of the nine Plane Line - Stance Line Combinations (three Stance Lines to each of the three Plane Lines per 10-5-0). The Plane Line - Stance Line Combination selected will reflect the player's Basic Stroke Pattern or its Variation, psychological preference, the intended Ball Behavior (Flight Path) or all three.
As a special note to those who have gone nuts trying to crack the code of CCW and CW in 10-5-0, the terms mean Counter Clockwise and Clockwise.
