Try stepping up from 5.5 to 6 and see whether that makes a difference in speed of progress. I felt there is a difference. Also, I would follow Accumulator's advice to try smaller pads. You wouldn't believe how much more efficient 5"-5.5" are than 6.5", and 4" are even more. Just be careful.
Furthermore, make sure your pressure is "just right". I am guilty of both bogging PC down with too much pressure and not using enough pressure. Marking pad / backing plate with one line across will give you visual indicator are you using too much / too little.
