TEPaul,
A tournament hosted on the last day the club is open, and out of season is hardly representative of the dual personality you suggest.
The course doesn't become "READY" in one day, REVERTING to normal play the next day. There are entry and exit time periods that the course must transition through.
At Seminole it's easy, no one is there and the course closes right after the tournament.
Try to find a northern course, in season with the Jekyll and Hyde personality you champion.
It doesn't happen.
A course doesn't intentionally yo-yo itself back and forth between firm and soft greens during the summer season for non-agronomic reasons.
However, if you could cite some northern golf courses that intentionally transition themselves back and forth during the
season for non-agronomic reasons it would be helpful.

Playing golf in 50 degree temperatures, combined with 25 mile an hour winds and rain, isn't quite the same as playing in the previous two day's conditions, and comparisons of ball flight and distance have to be viewed as strictly functions of adverse weather.
