We have a long course down here in my neck of the woods that's mostly just open holes with no obstructions and a lot of wind/elevation changes. You'll accidentally over-throw a solid 350ft pin even if you normally can't push past 315-320 on some flat-holes and on the contrary, you'll be struggling to make it over 300 on an uphill pin even if you can consistently throw it 350. Elevation makes a big difference. The tricky part is some holes seem to only go on such a gradual incline that it's easy to misjudge how much higher the pin is than the tee box.
