adjustment

Hi People! :D I've been trying to improve my backhand some time ago, and I'm getter better with the time. Now I can loop almost consistently, can do some spinny slow loops, and loop kills fro backhand. I think I can improve much more my backhand, but I think it's already a good enough BH to use...

Is this true? Do professionals actually use micro adjustment? I don't see how they would be able to do this every time.
