Dean:
What interesting info you put on here. I knew the design evolution of PFC was complicated and I guess I wasn't kidding. It would be most interesting if the club has (or will) put together the reasons why all those plans and changes were made over time. I guess for that though they would have to have all their board or meeting minutes going all the way back.
I have no idea why so many hole and sequencing changes were made over the years but if someone asked me to guess it would be that they were trying every way possible to work out a sequence to minimize "hill-climbing" on individual holes.
That kind of thing was one of the reasons my own course was changed so much in some sections and they felt like they solved the problem by bringing some greens down off really high hills. But after looking things over a few years ago I reminded them that they may've prevented the climbs up to those greens but in the end they didn't solve anything because they put the next tees up where some of the old greens once were and so they were going to have to go up those hills anyway to get to the next tee!
The only possible solution to the "hill-climbing" at my course I can see is instead of having to hoof it up a hill after your approach shot the later "green to next tee" situation we have now at least has stairs where the old "hill-climbing" on the individual holes used to be.
Wouldn't surprise me given PFC's topography which is quite similar to GMGC in that both have their clubhouses on very high hills, that PFC was trying to resolve the same thing we were----eg "hill-climbing" on particular holes themselves. Plus if the elevation change from approach to green is high enough (as it was on my course and may've been at PFC on some holes) it must have been pretty hard for some players back then to hit a ball up a hill that steep to a green.
