[69Cobra]

Obviously being halfway around the world I've missed out on some stuff, but could somebody tell me why these combo's are flagged? Being that I'm hoping to be out with you all next year I would really like to understand this system better. Now I know that if a combo goes -1.2 or more under its automatic but I'm fuzzy at best on the rest. Also how are they coming up with a 7 hp hit?
