Here are some of the numbers for wedges on green:
Up untill 23 feet use the pitchshot, from 24 to 95 feet use full shot type.
Rules: use it when green is curly at the start of the putt and relative flat near the hole. Never on bendy downhillers.
Pitches 17Y pitcher greenspeed 13 and 10 respectively (flat green, no wind):
50% = 8 feet, sp10=7 feet
60%= 11 feet, sp10=10 feet
70%= 13 feet, sp10=12 feet
80%= 16 feet, sp10=14 feet
Full shot type 60Y wedge (flat green, no wind):
40% = 28 feet sp13, 26 feet sp10
50% = 37 feet sp13, 36 feet sp10
60%= 49 feet sp13, 48 feet sp10
Full shot type is VERY VERY useful from ranges above 30 feet. You will see an increase at around 500% in holed putts from that distance. Wind has a minor effect. Elevation: do NOT land uphill and especially not downhill as distances then become unpredictible. Elevation rules are much like putting. The slower the green, the more advantage this method gives.
Generally about these 2 shot types: its only needed to read the last third of the putting line instead of the entire putting line. It makes it quite easy.
I would also like to recommend Tekoma's putting techniques for normal putting. That works also.
