I'll weigh in on this a little. Scent follows wind direction. Scent is not linear it spreads as it get farther from the stand. I'm not a graphic artist so take that into consideration.
In open country where you can see a coyote down wind calling can work if you can get a shot before the coyote enters the scent cone.
It can work in close cover where you can see the coyote before it enters the scent cone by using natural blocking creeks and pond work well as they usually have higher banks that you can sit on and have a good field of view, it also gives you a very small chance of getting back doored as there is no scent going into your blind side. We've had coyotes walk right past a hunter set up like this.
As you spend more time on stands and get busted you will learn coyote behavior, and like others have said there is nothing set in stone when it comes to hunting coyotes.
One thing after awhile you will get a feel for where a coyote will come from and even learn to direct them to where you can get a shot.
I've found that a lot of coyotes I call come into the call from the way the call is facing, the jury is still out on whether they are coming into the sound or I'm setting up my call to call into an area I think a coyote is going to come from.
When calling with the wind in my face I either set up with blocking behind me preventing getting back doored. It can be an open field, creek, pond or cliff but I've had coyote show up on the top of the cliff looking down on me. If I have a partner we sit back to back and have had coyotes circle 200 yards out and circle as close as jumping over my partners legs. A common scenario is to face the wind and have the caller set out 50-100 yards and hope the coyote will circle between the caller and the hunter. Dont set the caller too far out as one coming down wind into the caller will be too far out to shoot.
For most of my hunting I like to hunt a cross wind as it gives me a lot of options. Most of my calling is cold calling new areas.
Good luck, on your new adventure.
