Landing zones can vary drastically depending on green speeds, wind speed, wind direction, type of shot you are playing, and various other factors. You need to know the greens and how different shots will play on those greens.
Using your Pebble Beach #1 for example. One day playing in a windy clash, I was lucky enough to hole out for eagle there two rounds in a row. The two shots could not have been more different. One was played well past the hole and spun back down to the hole. The other was a punch played short that rolled up to the hole.
Another example of this was a day I was playing with two friends. All three of us stuck shots in tight to the hole at Congressional, but all the of us played completely different shots. One rolled the ball up to the hole after landing short. One stuck the pin with a shot that stopped dead in it's tracks. And the other used a slope in the back and spun the ball back down to the hole.
Normally conditions will dictate that one shot will play much better than the other shots, but the "color" you are seeing will not be the only factor in where you want the ball to land.
