Have a look at the picture below of Kia #12.... It's no "Andyson" but it'll have to do =). The pin at the back is the current hole location, the pin on your left (right side of the green) is a possible new location to express my point. Click here for full size
The two blue arrows represent the actual camera angles of this particular shot and approximately where the camera was located when the shot was taken (give or take a couple of feet) as seen by the forward and reverse views while putting.
The red and orange arrows show where the camera would (approximately) need to be if the pin were located at the front right hole location speculated by me.
To my knowledge (and I have been all over these greens) there are no camera angles that would even come close to the red and orange arrows, let alone give you a straight on look at the pin to avoid the nasty skewed read.
Now picture having to cover the full 360 degree spectrum around the hole location and at different distances..... I would speculate that there is probably 50-100 shots just looking at the pin alone for putting..... times 18 holes..... times x # of pin locations..... times whatever other factors I may not have thought of.....
Seems like a lot of work now that I break it down...... WOW!
