On behalf of Tee Direct Inc., JV Advisory oversaw the testing of various golf tee factories products to determine the durability of the wooden tees produced by each.
LocationTesting was conducted at the Family Golf Center in Oakville, ON, Canada, awarded the rating of “Top 100 Ranges in America” nine consecutive years by the Golf Range Association of America. All testing was performed on the grass hitting area and completed in early September 2009.
PanelA panel of 6 golfers with handicaps between 6 and 10 was selected for initial screening. All used their own drivers, which were all in excess of 460cc in head size. 70mm wooden tees were used in all cases. Each golfer was given 20 tees from the same supplier and hit balls from each tee three times or until the tee broke, whichever came first. After breaking a tee, they marked it with 1-3 stripes to indicate if it broke on the first, second or third strike. After this initial screening, the golfer with the highest and lowest breakage percentage were eliminated from further testing, leaving the four golfers with the mid range breakage results for the full testing process.
TestingThe four golfers were given a selection of 70mm tees which consisted of 5 tees from each factory. Tees were marked with letters so that the testing golfers could not ascertain the factory, but so they could later be identified in data collection. Golfers then hit balls from each tee three times or until the tee broke, whichever came first. After breaking a tee, the golfers marked it with 1-3 stripes to indicate if it broke on the first, second or third strike. If the tee did not break on the three hits it was not marked.
DataAll tees, broken and whole, were collected and then resorted by factory identification marks. The number of broken tees was recorded for each factory, and the total number of stripes marked on these broken tees was counted.
CalculationsFor each factory, the percentage of hits causing a tee to break was then calculated by:
A.subtracting from 20 the number of broken tees
B.multiplying the result of A by 3
C.subtracting the result of B from 60
D.adding to the result of C the total number of stripes on the broken tees
E.dividing the number of broken tees by the result of D
