There's a a lot missing from these stats. You're basing your estimations on distance only, but a very important part of the game is placement. Three holes at Maple Hill in particular stand out to me:
Hole 1
It requires about 400' downhill to clear the pond. Or you could lay up around 250 short, or play to the left or right. Once past the pond, the green is sheltered with a small opening. So to have any reasonable chance of hitting the green, you need to be able to place a shot near the opening for a short approach and then a putt. If you max out at 300, you won't clear the pond. So you have to play to safe, leaving you about 500' from the pin. The perfect 300 footer still leaves you 200 short. From here you need a placement shot, an upshot, and a putt. By distance alone, the 300 foot driver can hole out in 4, however, because of the placement requirements, it will likely be a five at best.
Hole 12
Here you're playing a long shot out of the woods, around a corner, and up a hill. To get an open shot to the pin, you have to throw about 400. From there, another 300 parks it. However, a 300 foot drive will require a short out shot to clear the woods. The third shot can reach the green with a putt for four.
Hole 16
This hole has two routes. The big arms are rewarded with a 400' water carry to the pin for a chance at at two. If you can only get 300, you have to play up the side of the water. You'll be short of the corner, which means you'll need a second shot around the corner, a third up shot, and a putt for four. By distance, you likely had this as a three.
