Applied Ballistics wind error?

I am having an issue with my AB kestrel and the AB app giving too much wind hold.

I compared the same inputs in 4dof and StrelokPro.

6 creed. 107 SMK. 3120fps
850 yards. 10 mph. 10 o’clock
68F. DA 4312. RH 41% Dof 104

AB. 5.0 elevation 1.3 wind
4dof. 5.0 elevation .8 wind.


When I swing the wind around to 3:00 . 850 yards. Same DOF

AB 4.9 elevation 1.4 wind
4dof. 4.9 elevation 1.1 wind

What am I doing wrong in AB?

Think that’s strange? My 4DOF gives me different elevation just switching from imperial to metric inputs. The odd part is, it converts all the values as far as I can tell, so it’s all the same data.
 
I’m not 100% proficient in 4dof, but what I’m seeing, you need the actual elevation and pressure.

When I use the elevation slider, the pressure moves.

Input your actual elevation and actual environmentals.
 
Ballistic apps don't have actual algorithms to properly calculate wind or spin drift. The short version is that they estimate and tend to over estimate. If you go to the threads for the Everyday Sniper Podcast and locate the one that talks about how to calculate wind the podcast explains this is detail. Very lengthy to explain and write out.

Yes and no. They calculate things very well with the input they are given. The problem is we cannot input enough data for the entire path of the bullet.

He should be able to get within a tenth or two with software and all his software should be close to one another given the same inputs.
