Chemat,
So far, saya tak pernah jumpa lagi course yang marking dia to the front green. Standard is to center of the green.
Memang kita susah nak gauge the actual distance sebab tak semua golfer tau the size of the green unless you play that course often...
Pasal over or short, banyak factor jugak..bukan aje sebab kita tak dapat actual distance from ball position to the pin/green, tapi swing factor pun ada...ada hari kita hit little fat shot, and someday with thin shot or perfect shot...as a result, kadang2 sampai, kadang2 tak...
Believe it or not, the position of the ball on fairway/before the green affect the distance..for example, if the ball is lying on uphill fairway, the position of the club face tend to be open up, so sometimes PW may end up become AW...or if you close the club face, PW may become 9 iron (again, depends on how you hit the ball)...
just no cents opinion...
Cheers!
