Unfortunately, the test IS subjective, but the photos in this link may help you. You pretty much don't want to see the black dot anymore. It's not just cloudy, but not really visible. If you think you see a hint of it, then note that value and add some more liquid and if it changes to be more obscure, then go with the higher number; otherwise, it's just your eye fooling you.
