Zero @ 2500ft DA, true @ 955ft DA...then.....?

I have a 6.5CM load that I chrono'd at my home range with a Density Altitude of 2540ft. I zeroed at 200yd, input the MV and DA into Strelok and all is well.

Then, I took a class yesterday where we trued our loads on the KD range. The DA at that range yesterday was ~950ft. Got my adjustment from Strelok based on my zero data, took a couple shots and then adjusted 5-6 clicks to get on the X at 400 yards. I trued (that's a weird word) in Strelok. Started banging steel at 1,000 with confidence, and even hit the 1,760 yard (24"x36" steel) target.

Now, when I go back to my home range, back to 2540 ft DA (or whatever it'll be on a given day), will Strelok be "off" because I've trued at the 955 DA? Or, does it automagically know to adjust back when I input the new DA? Or, will I need to "true" again once I get home?

As long as your environmental data was entered when you zeroed, again when you trued and now anytime you request an output from the software, yes, your zero should remain true.
