yea i have been doing this for a while, all tanks are zoomed in all the way each one of the tanks even shows the target at the proper range except the Sherman
i think i know whats wrong tho, when the Sherman came out if you zoomed everything all the way in it was prefect, but there was a glitch that blocked the view when not zoomed in, also you could see all around even when in the gun so they moved the eye back into the turret some but did not move the range finder back as well to correct the difference
i think the solution would be to move the range finder back , toward the turret till it reads right since you cant move the eye forward,
it also has nothing to do with the trajectory of the shell since all tanks that are shown have different trajectories, the range finders show more or less of themselves to make up for that, the distance is the same in every shot so the range finder should read the same in every shot even if the shell took more or less ark to reach its target.
