It may be, but for me it's always been the opposite! I could always copy faster than I can send, and still can -- this has become worse with age. I can still copy ~50 wpm if it's well-sent. I used to be able to just about send that fast with a Bencher or any decent paddle, but now find myself not really able to do that. ~40 wpm seems to be my top end without making multiple mistakes. Getting old is a bummer.
