@Oldfordman, the first 9 is noticably larger then the second 9 even without any doubling, also as far as I know MD goes in one direction, DDD make a bit more sense because the loop of the first 9 has doubling at the outside bottom of the loop. take a closer look and the first 9 is larger then the second 9 even if you were to take away any doubling MD or DDD they are different sizes.
