Most of the work is done ahead of time when the rifle and ammunition profile is set up in StrelokPro. This only needs to be done once. From there it's a simple matter of getting the Density Altitude reading which comes directly off my environmental ready by bluetooth, the range, wind and slope angle. It's a pretty quick thing and one I do a lot.
That table you see is something I do every 30 minutes or so, with fresh environmental data so that I have it on hand for a quick response time when needed.
Thanks for commenting, I appreciate it.
