I’ve spent some time and looked into the WGT engine. It’s actually pretty sophisticated. My simple algebra and calculus math is never going to “solve” it, and here’s the reason; MAGNUS FORCE.
Magnus force is the lift the golf ball experiences due to dimples on the golf ball and backspin.
A golf ball with no drag and no Magnus force would be a perfect parabola. But drag (wind and air resistance) distort the parabola. We can roughly model for that.
But Magnus force is hard to model. I’m not even sure how to do it, much less get my model to match WGTs model. If you’ve ever used an expensive ball with a high spin rating and watch it come up woefully short... Magnus got you. The extra spin and lift ballooned the ball up. I’ve verified this on WGT practice mode. If you track the apexes on shots you hit into the wind, you will see it too.
So... pausing here in my model creation. I either need to build a lot of if/then statements into my “plays like” formula to try to approximate Magnus effect based on wind direction and ball speed combined with ball spin rating and amount of backspin applie — or I need to rebuild the whole thing with a more sophisticated model.
Pausing here. Curious if others have tackled Magnus force and how they overcame it.
