Vertex Scoring System – How we calculate the scores…
Accuracy
Example Chart: Standard Deviation v Face Aim at Impact
Mean / Average = 0.0°
Increments = 0.1
Standard Deviation = 1.0
From this graph / chart you can see how % values are picked for accuracy.
0.0° = 100%
0.7° = 61%
-1.3° = 18%
Standard Deviation v Face Aim at Impact
Consistency:
Is measured in much the same way, except the Mean / Average is not known until a putt has been made.
Example: Backstroke Time
Putt 1: 0.65s
Putt 2: 0.68s
Putt 3: 0.74s
Putt 4: 0.64s
Putt 5: 0.63s
After the 1st putt the Mean / Average is calculated as follows.
0.65s / 1 = 0.65s
After 5 putts the Mean / Average is calculated as follows.
(0.65s + 0.68s + 0.74s + 0.64s + 0.63s)/5 = 0.668s
Then a similar chart to the one above (Standard Deviation v Face Change at Impact) is created, scores for each putt is generated and then averaged across the number of putts.
Putt 1: 0.65s = 96%
Putt 2: 0.68s = 99%
Putt 3: 0.74s = 61%
Putt 4: 0.64s = 91%
Putt 5: 0.63s = 85%
Consistency Average = (96% + 99% + 61% + 91% + 85%)/5 = 86.4%
