333ms
Top of backswing (P1) to impact (P3), in milliseconds (ms). Used to calculate backswing rhythm and impact timing.
854ms
Top of backswing (P1) to the end of the forward swing (P5), in milliseconds (ms). Includes the time to impact. SAM PuttLab optimal range is 650–900 ms.
2.10700 ÷ 333
Backswing time divided by time to impact. SAM PuttLab optimal range is 2.00–2.20.
0.39333 ÷ 854
Time to impact divided by forward swing time. SAM PuttLab optimal range is 0.35–0.43.

Practice settings
Every sound follows the putter head, so you hear the way back, the change of direction and the speed into the ball, then a clear beep at impact. Pendulum sweep climbs going back and falls into the ball. Swoosh stereo travels right on the way back and left through the ball, so use headphones or two speakers.
How to use it
1. Set your tempo with a preset or the sliders.
2. Choose a sound and press Start tempo, or the space bar.
3. Two pips sound before each stroke. The takeaway (P0) starts 0.5 s after the second pip.
4. Press Full screen for a life-size view of the stroke on the ZERO ZERO template.
Floor modeLife size
Lay a monitor or TV flat on the floor, open Floor mode and putt alongside the ghost head. The screen shows the ZERO ZERO template at true size, and the head rides the arc at your SAM tempo, the face rotating 12.3° per metre, so it is 1.23° open at P2 and 3.27° at P1 on a 10 ft putt. Calibrate once with a ruler, nudge the impact mark in line with your ball, pick the putt, and load a top-down image of your own putter head in Setup. The full template needs a screen at least 82 cm wide; a 43 inch TV does it.
