Yes, your scope clicks will increase as you increase in range. For example, if you adjust 1 click up for a target that's 700 yards away, it will be 7 x 1/4" or a 1 and 3/4 inch increase in height at that distance. I guess the simplest way to figure it out is to just multiply the "multiples" of a hundred. So for your target at 800 yards, each click would be 2 inches in elevation or windage.
I don't think you are wasting your time at all. Being on at 100 yards and then doing some math will help calculate a good starting point, and then you can tweak the adjustment a bit in case there is wind.
I would say you are on the right track!
