MainzMan: Whatever, I'm happy to accept what Dazza says. It makes sense and I'll continue to believe it until someone offers a viable alternative explanation rather than just saying he's wrong.
O.k., I was wrong concerning OLY.
Alas, we have discussed this subject ad nauseam concerning other courses. In all cases (before OLY), the scorecard length is to one of the pins, not to green center.
STA#10 is the most prominent example:
From the whites, it shows 330 yds. These are some second shots from the tee (see top left) with indication of the real distance:
1) to the front pin, 317 yds (visible from the blue dot before the shot)
2) to the left pin, 330 yds (=scorecard length).
The minimap shows that this pin position is still in the front half.
From the camera behind the green, the green yardages are 316 (front) and 365 (back), thus green center would be at about 345 yds.
It is even more apparent at STA #1. There, the back pin marks the scorecard length while the front pin is 20 yds shorter.
Numbers from the tips:
Scorecard = back pin: 375 yds
Front pin: 355 yds
Green extension: 344 to 387
Green center: about 366 yds
