just an example, check the forum pages too------->
When you've a putt that for e.g is 20 ft and 5" uphill, thats 25!
lf your on a tourney grn, from 25 less 30% gives you the distance, give or take! also look at the putt line, if it changes colour maybe from red to sometimes yellow, then there's a big slope downhill, so aim for the top of the slope and allow for the roll, it's going to go rapidly downhill, from black to blue its going up, so allow a bit extra. (The old adage, never up never in) reverse view look at the putt and drag your cursor past the hole and see if the elevation changes and your putt line changes colour too.
Tourney grns overall distance less 30%, VF grns less 20%, fast Grns less 10%, Standard 0%, slow add 10%.
There are a lot of great tips as mentioned in the forum---->
