I ran it through Strelok Pro, and the answer is "ugh".
If you zero dead on at 36 yards you'll be two and a half inches high at 100 yards and essentially have a 300 yard "second" zero, expressed as 36/300. This is why the Army guys used to do a "battle sight zero" back in the old days where they only had irons to work with. You could hold dead on to an enemy soldier and hit them just a couple inches high or a couple inches low out to 350 yards or so. That's the "maximum point blank range" iron sight setup your uncle was rocking in Grenada back in '83. It's great if you only have a single point of aim to work with, but in this case it would make your BDC dots pretty useless.
If you want to simulate a 100 yard zero but only have 36 yards to work with at your indoor range, sighting in 2.5 inches low at 36 yards is a good initial offset that SHOULD get you almost to a 100 yard zero. Of course you would want to confirm and fine tune at your first opportunity to reach out to 100 yards, but it would at least get you on paper.
