Try -
distance +/- elevation = calculated yardage +/- wind
calculated yardage/club’s FBS yardage = percent power to hit
Elevation is calculated -
greater than 100 yds: elevation shown on aiming placard/3
less than 10- yds: elevation shown on aiming placard/4
Wind is calculated many ways. A basic table is displayed wind speed x:

Take the wind and multiply by the percentage then add or subtract from calculated yardage
You will need to adjust the wind effect by the direction it is moving. Use the clock system:
