Cud’s must touch the rim and this example does. Then it turns 90* southward. This type of cud is called a linear cud.
Nice cud. Congrats. Edit: It is my understanding that all cuds include the rim (edge). If the die break doesn't include the rim it is an interior die break (or die crack if the chips are small). Is an interior die break what you're referring to as an "interior cud"?
It’s not so often I find someone important that see’s’ things my way. I agree with your answer. I think I just joined the NUT club
