It's very simple:
You take the cosine of the decent angle of the club you intend to hit. Divide that by the Oblate Spheroid angle on the ball being struck, which is easily calculated by the coefficient of compression times the club head speed divided by the static loft or 0.8732 multiplied by the dynamic loft. You take that result and multiply it by the distance you would normally hit the club. Then add that to the original figure, subtracting 1/5th value of the wind speed squared, divided by the barometric pressure. Then you multiply the coefficient of the up current or 1/3 the coefficient of the down current depending on if you are right or left-handed. Your use the Pythagorean theorem to determine the overall length of the ball flight. Which is really just a simplified version of the longest leg of the right triangle. Of course that number needs to be adjusted to account for the arch involved in the flight. To factor that in all you need to do is calculate the circumference of the Earth at the exact point at which you are standing and divide the original distance times 2π times the tangent of the height of your left wrist from the ground and the shaft length of the club. We’ll ignore the actual sole thickness of the club because while it has a factor in the calculation for our purposes it won’t affect the ball flight enough for us to include it. Once you have that result you simply multiply the coefficient of slippage which can be looked up off any chart based on weather conditions and temperature. You determine the derivative of the angle of attack at address and then simply add in the number of calories you normally burn each day divided by what time of day it is and then put factor in to select your club.
So, as you can see. It’s really very simple.
When in double you can always just have Bryson DeChambeau calculate it for you.
Every credit card payment that I make to a government agency (that I can think of off the top of my head) passes the surcharge along to me. (City taxes, county taxes, state medical licenses.) Paying 3.5% on a bill for thousands of dollars is a lot of money.
(I can often find a legit way to avoid it. Handwritten check still accepted at county office. Online state medical license will accept electronic check for a processing fee of $0.75.)
