That's not true at all. Even at 500-700 yards, wind holds can be significant (as in off target). That changes second by second. I can tell you that even as a decent shooter with a better spotter, when the spotter makes a wind call, the slight 1-2 second delay before I can actually press off the shot can be enough where I need to change the hold slightly from what he said to make a good hit. Over this distance, there will undoubtedly be some fishtail winds and dead spots that are changing on a per second basis. In this case, I'd expect you have a team of spotters reading the mirage at several distances to target, and one lead spotter that is integrating those into the wind call for the shooter. There's also some new tech that's aimed at this problem actually where instead of getting a wind read at one distance, it measures the wind over the entire distance and gives you a hold based on that. Very fancy stuff, they may have used that in this case.
