Nope, that method is perfect except for speed 6. In my experience, speed 6 doesn't do any better than speed 5 but it DOES cause the product to flash too fast and/or cake up the pad. This may be your problem. From now on, stick to 5 and you should do much better. You are correct about not continuing after it dusts. Once it dusts all you are doing is inducing micro marring, you are better off stopping, wiping the residue off, and restart.
Using speed 5 will make the process take longer and if you use too much product, it will feel like days before it dusts but your finish will look a lot finer this way.
