The extra letters go after the actual title. If you get an average of 180-190 you get CL. The MCL, or CL go with every level.
They did add the C a year ago to the front of the titles. I'm not changing mine though as Smudge and Cider got the MCL on novice, Cider MCL on advanced and excellent. That already shows it's not CKC, AKC or UKC rally.
