If you are set on a yardage turret, I would base it on 7000', 30 degrees, 30 % humidity
It comes with a MOA cap out of the box. Large marks at MOA, small marks at 1/4. And every third is numbered (0,3,6,9,12,0).
One of the points of the yardage caps is to eliminate the cheat sheet and math between the range and optic. You won't be in a perfect world shooting and will have to judge windage and other variables. But with the base line yardage scale on the cap, your a little closer to being there quicker.
