Putter — later

A putter needs a different method from a full swing. One good option is start-line analysis: film from behind the ball, place a target line, and measure whether the ball starts on it and how the face and path move through the stroke.

5 Patterns across reports

  • Tempo: every report so far measures close to 2:1 (~2:1 (0.45-0.6 s / 0.23-0.3 s); ~2:1 (0.5 s / 0.25-0.3 s); ~1.9:1 (0.50 s / 0.27 s); ~2:1 (0.60 s / 0.33 s)). The tour benchmark is 3:1.
  • Head motion: the driver reports show the head moving down and toward the ball (down-the-line) and toward the target (face-on) in the downswing.
  • Finish: balanced and held in every report. It's a consistent strength.
