Is golf swing a double- or triple-pendulum action?

The Pendulum Stroke's Missing Dimension

I'm not familiar with the 'double or triple pendulum action'. However, I can tell you that, in general, Homer Kelley felt that the whole 'pendulum idea' was deficient.

By definition, a pendulum operates in a vertical plane -- swinging two-dimensionally downward and forward as it seeks its lowest point. In contrast, we golfers operate in an inclined plane, swinging three-dimensionally downward, forward and outward as we seek the lowest point.
