Which course?
Should have been Wolf's Creek.
Mind you that scorecard yardage may be off in some different ways, dependent on the course's age. STA is different to OLY which may be different to Chambers Bay.
The most precise way to get the correct yardage from the tee is the blue dot on the mini map: On hovering over it, it will show the correct number regardless.
For Wolf's Creek #18, indication from yellow tees (practice) is 272 yds, while the correct yardage is 261 - 11 yds less!
