(Yes indeed, there is an impact with head and tail winds, especially in the higher winds seen at SA and RSG. At those courses if I have a 15 - 20 mph head- or tail-wind I add or subtract about 5% to total distance. If you have a strong tail wind and a downhill putt, you may want to take off even more!
The best way to see this in action is do some putting on SA #9; go to WGT COMMUNITY/ GOLF COURSES in the top menu bar and navigate to SA #9 and hit play now. Once on green, ignore the pin hit some putts directly into or away from the wind, using 100% of an appropriate putter scale to keep the ball on green. Since the green is Standard speed, you should get close to scale distance with no wind.)
I have fairly good comprehension skills. This explanation is about tail winds speeding up a putt and head winds slowing down a putt.
This explanation does not say anything about effecting a putt to the left or right. So, if this is all that WGT says about programming so far, this issue is still open.
Also, the question of resistance from S balls and more distance on putts with D balls is something this explanation doesn't touch on.
In my mind, this whole discussion is about head, tail, AND cross winds. There is nothing about cross winds in this explanation. These three factors are the factors that would be controlled by the wind. Maybe the wind only controls head and tail winds. I am curious why cross winds were not even mentioned.
I will try this head and tail wind data with my putts...... but so far.... I have only tried this added factor for cross winds and it does not help my putt at all so far. I only try this when I have a birdie try. I have missed a lot of birdies trying to add this cross wind factor in.
It is great that the piece about the wind is found from WGT but my query to them should give more info on this..... but..... WGT has not replied to my query. Maybe this cross wind point is something that they can not answer so quickly because no one has ever asked before.
I will give them another try to see if they will reply.
By the way, I never play practice games. My average is 65.5 and I could care less about some stinkin putt percentage. Like I said, I only play for fun, not stats.
