There is one for every green speed
distance + or - Elevation X Factor
it is:
1.15 for Slow
1.05 for Standard
.98 for Fast
.88 for Very fast
.78 For TM tourney
.68 For Legend Tourney
These work for Flat And Up Elevations
For Down elevations of -1 to -3 I decrease the factors by .03
For Down Elevations -4 or Greater I reduce them by .05
There are other factors that work that people use too.I can usually stay close should I miss using these.
