I'm going to go out on that same limb and say you should practice. Yu Nakamjima has a video on how to make a layer for 2x2 in just a few moves. I'm willing to bet if you just follow his video and then get all your CLLs sub1.5, you should be sub3 in no time. You should also be able to see which CLL group you have at inspection, and if you really practice know which CLL you have at inspection.
