+1, but which course and hole?
Ah, it's from the hole info of KIA#1!
There, the green is approx. 30 yds deep and the front flag is about 10 yds from the front green edge, see replay.
Thus, an "information" giving three different green fractions and an erroneous total depth of 46 yds looks useless and wrong to me.
At least the region of the front flag is correct, alas unprecise.
What to read from it, as the OP asked? Nothing, unfortunately. The precise information is given with the "distance from the hole" at the mini-map's blue dot and (mostly) at the upper screen edge. For green dimensions, take the reverse green view.
BTW: These measurements are ommited on other courses.
