RJ,
Interesting take on platforms vs lay of land. In some ways, we have to ask if the definition of distance control is the possibility of achieving success or is it the degree of penalty recieved when you miss?
Generally, I think the platforms are bigger tests of distance control on the penalty front, as they result in frequent uphill pitches and sand shots. Lower, ground level greens would have easier sand shot recoveries, but more INTERESTING chipping recoveries.
The lower greens certainly add the option of the run in shot, but both types, with the contours on the interior (and with run on greens, just in front of) might have the same chance of success. Perhaps low greens, with one added option are a bit easier because of it? Or is the extra option just mental comfort for some and the shot remains equally difficult?
