The index for quality consistency over a matched set of clubs
CP Index ^™ is the standard to identify the problem clubs in the bag:
1.  Performance Benchmark - how can a golfer shoot low scores when their equipment is ill-fitted and not built with quality consistency (club-to-club), from the Name Brand OEM manufacturers, or from cut-and-glue clubmakers?  Not all is created equal, even when cosmetically two clubs look identical.



Set Purchased From Golf Retailer
CP Index ^™ = 0.6 ... ABSOLUTELY TERRIBLE, so prepare yourself for an increase in your stroke average
2.  Low Quality - review the following chart and look at all of the club specifications circled in Red.  These are the numbers which are not correct for a matched set of irons and wedges.  On the far left side of the chart is a depiction on how this set would perform club-to-club if hit on a mechanical robot.  Look how the clubs begin to group together, which contributes to an increase in % Error.



Tour Quality Set From Golf DNA ^™
CP Index ^™ = 8.7 ... NEAR PERFECTION, so prepare yourself for a decrease in your stroke average
3.  Exceed Tour Quality - review the following chart and look at all of the club specifications with no numbers circled in Red.  The complete matched set of 'balanced & blueprinted' irons and wedges have been assembled and tweaked to near perfection.  On the far left side of the chart is a depiction on how this set would perform club-to-club if hit on a mechanical robot.  Look how the clubs exhibit a consistent distance gap between each golf club, which contributes to a decrease in % Error for lower scores.
