Lynn, I know what a switch is. What I do not see is what a switch over a 12 hour period has to do with a 10 Minute relay. I also do not see what it would do to a target when the range is as flat as a pancake.
You say the place is so much tougher than we have here, but it can be read. Then you say guys from CO come to your range to shoot small groups. Then you say our range that sits on top of mountains has mountains blocking the wind and so it is easy. Then you say the range where these guys come from that has mountains 7 times as high as the ones here, and somehow that makes it tougher.
Now either they block the wind, or they don't. LMAO. Either the trees help, or they don't. Here's how I see it. Each range has good days and bad days. On the good days, guys who come prepared shoot small groups. I've seen it too many times for it to be chance. This is because they come prepared all the time in anticipation of shooting small if they might get a lucky relay. Perhaps you should prepare a little more and then go shoot some small groups when Your good day comes.
Now, I have to tell you, I got a terrific laugh out of one of your statements above. I've seen this before by a "Wind Reader", and it was hilarious.
If you hold for center on each shot the guy sitting next to you can watch your spotter disk while watching the flags.It gives him the advantage.
Tell me, how does someone know you are holding center? Does he just assume this because some people do? I suppose that's possible but, what could you possibly learn from that persons gun? How do you know how well it shoots? How do you know how much they've adjusted. How do you know that person isn't messing with ya, aiming all over hell? Ya see, I ask that cause I've had so called wind readers use my sighters in the past and I DO NOT aim my sighters in the same place. If a person beside me shoots one out slightly, I am likely to aim there and shoot one myself. I often aim 9-9 and even go up and down, just to make certain I do not have a "Same Spotter" and it not get moved. Ya know, the lower/raise thing but don't move the sighter. See I don't like them.
Then, once upon a time, I had a wind reader shooting beside me and another one spotting for them. The one spotting was waiting till I'd shoot, then "Reading the conditions" for the shooter by looking at where my bullets went. It was comical. See, I wasn't adjusting my scope, but not aiming in the same spot for any two either. (Very common for me). When it's all said and done, I don't put my crosshairs in the center of the target anyhow. But anyway. So this person was calling shots and then they'd adjust, then wow, it came back now. Musta been a quick switch. So then I'd shoot where they were expecting and it would confirm their analysis. And on went the sighter period. Now at 12 sec, they shot their last sighter, and I shot mine at like 1 sec (I count down). I aimed mine just a little farther out than their last one had gone, and low and behold, I listen to the spotter say, look, it seems to be picking up a bit... yada yada yada. It was hard to not burst out laughing, but I managed not to. I went on to the group shootoff winning both Group and Score, and they shot out in the 8 ring. Some of the most fun I ever had in shooting. I wish I'd gotten a video of that.
The moral of the story is; If you decide to use someone elses sighters, don't use ole 4Mesh's. Don't use anyones who's gun doesn't shoot. And watch very carefully how many clicks they put on every shot. Know their gun and how it behaves in a sighter period. And most of all, if you're talking out loud, don't ever use someone else's sighter to confirm your guess. It's bad karma.
As for Jim Hardy, he said he reads wind in F-class very conventionally, and did the same thing anyone else does when he shot benchrest. I didn't see anything unusual in his post and he didn't exaggerate anything. I really don't know why you keep referring to it. I said the F-Class examples do not apply to our record strings. I don't care about wind reading in the sighter period. The sighter does that for me. Ya know, I also don't need years of F-class experience to understand it. I've shot sighter periods galore and it's the same thing as F-Class. Shoot, and they spot it, then adjust. It ain't rocket science Lynn.
