Many golfers believe an out-to-in swing causes a slice and an in-to-out swing creates a draw. Modern biomechanics shows this is only part of the story. Club path alone does not determine ball curvature. The decisive factor is the relationship between the clubface and the club path at impact.

Club Path describes the direction the clubhead is moving relative to the target.

Clubface Angle describes where the clubface is pointing relative to the target.

Neither value alone explains why the ball curves.

The critical formula is:

Face-to-Path = Clubface Angle − Club Path

Example:

Clubface: –6°
