Am I correct in assuming that it takes just as much chlorine to to maintain a FC level of 8 as it does to maintain a FC level of 4? 
Am I correct?

If all other factors are the same I would say yes. To raise FC level say 1ppm would take the same amount whether raise from 7 to 8 ppm or from 3 to 4ppm. But if there is some chemical reason why it would someone will correct us both on it

As long as you maintain the same FC/CYA ratio, then your daily loss to UV light (the largest contributor to FC loss) should be roughly the same. Algae or excessive CCs will increase the FC loss rate. The FC loss rate to UV light is based on the amount of hypochlorite ion (OCL-) in the water and the concentration of hypochlorite is proportional to the FC/CYA ratio.
