Bare en "liten" presisering - igjen - for hvordan "stimpen" måles...
How to Use a Stimpmeter
Equipment Required:
• Stimpmeter
• Three golf balls
• Three tees
• One 10- or 12-foot measuring tape
• One Data Sheet
Step 1 Select a level area on the green, approximately 10 feet by 10 feet. (A simple means of checking for al evel area is to lay the stimpmeter on the green and place a ball in the V-shaped groove – the movement of the ball will indicate whether or not the area is reasonably level).
Step 2 Insert a tee in the green, near the edge of the area selected, to serve as a starting point. Holding the Stimpmeter by the notched end, rest the tapered end on the ground beside the tee, and aim it in the direction you intend to roll the ball. Put the ball in the notch and slowly raise the end until the ball starts to roll down the groove. Once the ball starts to roll, Hold the Stimpmeter steady until the ball reaches the putting surface.
Repeat the same procedure with two more balls, keeping the tapered end on the same spot.
Step 3 All three balls should come to rest not more than 8 inches apart. (Should they be farther apart than that, the Stimpmeter may have moved too much during the series, the balls may be damaged or of inferior quality, or unusual conditions may exist. In any event, a pattern larger than 8 inches is of dubious accuracy, and the three-roll series should be repeated.)
Assuming the balls stop within the prescribed 8- inch limit, insert a second tee in the green at their average stopping point. The distance between the two tees is the length of the first series of rolls.
Step 4 Repeat Step 2, using the second tee as a starting point and the first tee as an aiming point. (In other words, roll a series of three balls along the same line, but in the opposite direction.)
Step 5 Repeat Step 3, thereby establishing the length of the second series of rolls. Step 6 Measure the two distances – for the first series and the second series – and calculate their average. Record this as the speed of the green.
Note: Should the difference in length between the first and second series be greater than 18 inches, the accuracy of the resulting average may be questionable. The area selected for the test may not have been sufficiently level – or sufficiently representative of the green – in which case it is advisable to select another area and repeat the test. Sometimes a green may be so severely undulating or sloping that a level area is simply not available (which the data record should indicate).
