If you're talking about the old pin ( on the left side) .. 20-30 feet long is fairly normal, and definitely better than being 5 feet left or right of the pin because it's a fairly straight putt. Anything short of the pin is crazy fast...not impossible, but incredibly tough to judge your power consistently.
A few times, I've wound up very close ( once for eagle) by playing 3-4 yrds left of the pin and landing right on top of the slope. IF you can hit the spot, the ball trickles down the slope and breaks right, toward the pin.... short of that spot, though, and the ball stays on the wrong side of the hump or rolls back off the front of green, leaving a brutal chip/pitch that might still go 20' past the hole.
