I am running an EOtech 511 on a 7" 9mm AR pistol and would like to sight it in for close range. I have found that with the ammo I use if it's sighted in at 15yrs it should re-zero at 100yrds. So if each click of the adjustment knob = .5moa@100yrds would it be .25moa@50yrds or does it work differently than that?

That sounds correct....half the distance, twice the adjument.
