It seems like every CW QSO I get into, I butcher a word or two, or more. Sometimes I send a couple of dits and correct the letter, sometimes I correct the whole word, and sometimes I just let it go and keep sending. Each mistake is a judgment call, and sometimes I find myself getting jammed up making the call. It's a new skill I'm developing I guess. It's still a conscious decision. It boils down to whether the OP on the other end already knows what I mean. Does this skill get developed to the point of unconscious action? By the time that happens do you make so few mistakes that you don't need the skill any longer?
