Range Ball Data vs Premium Golf Ball Data
When using the GCQuad or GC2 outdoors, it is important to note the difference in data of a range ball vs a premium golf ball.
Below is a data set from Todaysgolfer.co.uk, which shows the results of their in house pro testing range balls vs premium balls.
The most drastic change is related to spin numbers, specifically in wedges. This is primarily due to the hard covers used by standard range balls.
This hard cover exacerbates low spin in wedges due the lower swing speed, which in turn causes the grooves to bite less. On a premium golf ball, this lower swing speed with wedges is compensated for with a softer outer cover.
This also explains why we see these data discrepancies dissipate as club lengths become longer. An iron will cause the range ball to spin more than a wedge due to the higher associated swing speed and smash factor. Essentially, the iron grooves are more effectively able to bite into the hard range ball thus producing higher spin.
Once a golfer works their way up to a driver (where no grooves are involved) we essentially see that spin discrepancy disappear.
