Modern golf course mowing equipment has certainly made an impact on how our courses are maintained. Unfortunately, it has also led to an arms race of sorts, how low can you go. We mow fairways at 3/8ths, tees at 1/4, and greens at 1/8 th or less. This has led to many other problems. I can say I used to think the way to make a course play fast was to mow everything tight, it took awhile for me to learn that a fairway mowed at 5/8 ths and kept dry was a lot faster than one cut at 3/8 ths and kept wet.
Matt,
Although I would agree that many irrigation redos concentrate on increasing the amount of water delivered, they also should increase the uniformity, and actually in the hands of a skilled user, should result in a dryer course. Most courses get watered based on their bad spots, thus an older inefficient system may result in more wet spots trying to get rid of all the hot spots. A new system with improved uniformity should reduce those wet spots, but like you said, if it allows the user to put out a million gallons a night, they just might do it.
