user3149: I'm currently a Class B with a TT rating of 2100. I would like to aim to become a 2100 with norm of Candidate Master. What tactic rating does a CM usually have? How strong are Expert class chess players in tactical calculation? 

user7534: While you cannot get to Candidate Master on tactics alone, most Candidate Masters have much higher tactics trainers ratings than you do. For example, Candidate Master Mago has a TT rating of 2602. While you should continue on your TT journey, you should also study master games, endgames, and positional play.
