In my experience in socal, firm and fast is tends to be harder work. The super needs to walk the thin line more, and all too often some of the lesser supers (or less "driven"), tend to play it "safer" by watering more. Some of it is job preservation, occasionally it's less work.
Firmer conditions out here require some more supervision and hand work, and many clubs will not allow the super to do it (green is keen).
Funny, I'm involved with a couple of courses that have cut to the bone, maintain with (relatively) small budgets for this area, and are producing very good, and pretty good conditions. We're heading back to the future, with less (over)watering, less manpower, and realistic expectations. Should be interesting to see who survives the change
