No offense Carl but NO computer is going to do a better job determining pin location than experienced eyes on the green. The minute the article mentioned "root zone moisture" and "salinity" I threw up a little in my mouth.
Here is how locating a suitable pin location happens 99% of the time: A person walks out onto the green, with a rotation of some sort (Front to back...A-F), looks at an area of the green for a pin location that doesn't have a lot of old holes healing, or a bazillion pitch marks, locates a spot that is "fair", and cuts the hole. Human eyes see the localized dry spot forming, human eyes see the areas that will be hand watered later in the day, human eyes know a tournament is later in the week and will save a "special" pin location.
