The best tour caddies are doing this math. Now you have one too.
Your rangefinder accounts for slope. But slope is responsible for less than 20% of the total adjustment you need to hit the right distance. Wind, temperature, humidity, and altitude make up the other 80%+. And even with slope dialed in, half of all laser reads are off by 10 yards or more from the number you actually need to play the shot.
