gerry,
Since WGT took away the "Zoom" mode this has become a more difficult. Previous posts, from top players, suggest the following:
1. The flag stick (on every courses) is 7 feet tall
2.For most views, the box that contains the range and elevation info (above the green/blue triangle) - assume that the horizontal box dimension is 10 feet wide (unless that is OBVIOUSLY TOO MUCH) - {gotta employ your eye and common sense here} {If you want. pull out a ruler & measure the height of the flag stick - 7 feet tall see #1 above & use that instead of the 'box']
3. Calculate your offset: (see above chart for 45 degrees} - I use wind speed/10 X distance to the pin for "laydown" head/tail and pure crosswinds
4. Using #2 & 3 above - offset your aim point (into the wind) & hit - i.e. if you figure that the offset is 20 feet - this equals 2 "boxes' (into the wind) - put one corner of the 'box' on the flag - hold a sharp pencil point at the other corner of the box - move the whole box over, placing the edge that used to be against the flag over your pencil point. Move the pencil point over to the other edge of the 'box'. - that point is 20 feet. Now move the aim point to your pencil point (= 20 feet) and wham away.
May not be perfect, but this method is used by Tour Legends (i.e good enough for me)
Try it - you'll love it : - ))
P.S. Do not claim to be anything other than (a little) above average, and I am not a Legend or WGT Nation person!!
