This app uses the common P-system:
P2, P6, P8 = shaft parallel to the ground;
P3, P5 = lead arm parallel;
P9 = trail arm parallel; P1 address, P4 top, P7 impact, P10 finish. (ModelGolf's original 10 positions use
shaft vertical for 3, 5 and 9, which lands a little later in the backswing and earlier in the downswing.)
Colours:
lead arm,
trail arm,

club. Segment ratios after ModelGolf's "Ideal Dimensions" chart (
