Face-to-Path Simulator

Understand the new ball flight laws. Path dictates start line, Face-to-Path dictates curve.

+ is In-to-Out, - is Out-to-In

+ is Open to Target, - is Closed

Assuming center strike. Gear effect overrides Face-to-Path on off-center hits.

The D-Plane Rules

  • The ball starts roughly 85% where the face is pointing at impact (for irons, ~75% for driver).
  • The ball curves AWAY from the club path, relative to the face angle.
  • A negative Face-to-Path value (face closed to path) creates draw spin.
