genorb: So when you hit the ball with a long iron, the velocity of the ball is higher and the wind has more effect on the ball but, as you pointed out, the trajectory is also more flat compared to a shot with a short iron (or a wedge). So on long shots, even if the effect of the wind is higher, the trajectory being more flat, the wind has less time to act on the ball. On short shots, the velocity of the ball is smaller and the wind has less effect but the trajectory being more curved (the trajectory is higher, so the difference between the arc length and the horizontal distance travelled is larger) and the wind has more time to act on the ball.
This is true in WGT, but, having played IRL for many years, I can definitely say WGT's parameters for such are definitely off.
I.e in Real Life, if I have a crosswind of 10-ish mph (guestimate) I play a wedge shot from 90 yards about a flag stick off to the side.
If I was playing the same shot from 170/180 hitting a 5 iron, I might play the flag stick plus a few more feet.
In WGT, you really have to take it much further. Again, thins is why I made a comment about players and gamers..players like me will struggle with this, gamers will figure it out.
Who knows, maybe it's me and my old sticks that play IRL.
Like we were having a discussion in our CC...heck, if I could figure out how to make 9 out of 10 puts with my driver, I'd do it! :)
