Brent - I can't make heads or tails of this talk either, but I do know that a couple of years ago the superintendent from St Andrew's gave a talk in Guelph at the turf institute here and similarly noted, if my memory serves, that he hadn't put water on The Old Course in over a decade (except for that hand watering of greens), and the other 'inputs' were also similarly sparse/almost zero. It brings to mind the notion of the virtuous circle instead of the vicious spiral.
