green speed

Green speed , is a long time ago a man named Edward Stimpson who, in order to make
the 18-hole green speed consistency, invented a measuring instrument used to measure
green speed, in fact, very simple to do a metal ramp is definitely low-tech! is an
aluminum plate, 36 inches long, with a V-shaped groove, the flat slope on the
greens, the measurement will be raised to 20 degrees of aluminum angle, then ball on
the top of the slope, generally to ensure that the ball rolled down from the top to
reach the bottom at a speed of 6ft / S, and then watch how far to scroll (in units
of Feet), with the rolling distance to identify the speed of the greens. For
example, rolling a 10Feet, green speed is stimp speed 10. This approach has
continued to the present, so the measuring instrument is called the green
Stimpmeter) indicates the speed of the greens is stimp rating or call stimp, now
Sidi spectral index is also used to compare different greens speed.
