Yeah, another one. Sorry. I only started playing here about a month ago, but quickly realized I'd need some kind of aid. Being an engineer (retired), I thought I might write a program or spreadsheet. Of course, I searched first, and found quite a few. Most with different answers to the same questions. So while I've looked at all the other resources, I'd like to do something a bit different. It's not ready to it post, or anything, but thought I'd discuss a few things here, to get information to help me.
First, since I'm an engineer, while I like rules of thumb and such, I like to understand the physics behind things. So, where possible, I'm trying to start with the math and physics involved in something, then compare it to existing solutions, and try to adapt it.
A prime area of interest (and confusion) is in how headwind and tailwind change a club's distance. Most calculators (for WGT anyhow) add or subtract normal yards by one or more constants, adding or subtracting from 0.38% to 0.56% per mph per yard head/tailwind to the distance. Making it directly proportional both the wind speed and carry distance. Yet real-world calculators come up with something completely different, a distance modification which is basically proportional to hang time, rather than distance. Take any of these real world programs, and it usually works out that the maximum change in distance from fairway shots is from a 7-iron, not a 3-Wood, and therefore not based on distance. And also that the wind effect is not linear, either.
But, just because something's true in "Real Life", or in Theory, doesn't make it true in WGT. Who knows? They could be using really complex, real-life calculations, or very simplified calculations for all these values.
Anyhow, the area I've found the most disagreement from theory and real-life to WGT is in wind-modified distance. Anyone have any thoughts on this?
BTW, please don't bother looking up my golf games, scores and statistics here, as a rating of my worth in discussing this; I'm just starting in WGT golf, but have been one helluva engineer for over 50 years.
