Back when I worked at the "old" Microlog Corp in Gaithersburg MD in the late
70's, we found that a lot of rigs couldn't be keyed much faster than about
50 WPM. Key click filtering etc., made mush of the faster CW. A keyed
string of dots looked like the output of a half wave rectifier ! To get
around this limitation, in order to run >100 WPM CW, we'd revert to AFSK
keying, copying the Mark frequency only.....worked like a proverbial charm.
It was like having our own private encryption system as nothing but a
computer assisted copy system could decipher it. We never really asked if
it was legal though.
And, to my knowledge, there was and still is NOTHING out there as good as
the decoding algorithms those programmers wrote. (The main one just
happened to be the president of the company.) I tested every piece of
competitive equipment I could get my hands on to prove this point. Microlog
was the absolute king-of-the-hill for CW copy, hand sent, bug sent or
otherwise. In order to fool it, you had to purposely send "rotten" code.

Now, that made me laugh.

I agree with Dave that it can be counterproductive to run high speed in a
contest. You lose too many contacts with stations who can't copy that
fast.
I used to be able to copy 50 wpm pretty consistently in my head and I
have a 40 wpm W1AW code proficiency certificate. But it makes no sense
to go that fast in a contest unless you are content to work only other
QRQ stations.
I think around 30 wpm or so is reasonable. Even operators who can't go
quite that fast can probably get your callsign after listening for a
minute. Then when they call you at 18 or 20 wpm you can slow down to
work them and then speed up again.
Years ago Chuck W1WPR, the chief op at W1AW, was listening to a QSO on 40
meters where they were motoring along at 70 wpm or so (obviously using
keyboards to send). So Chuck recorded them on the reel-to-reel tape
recorder and later played it back at half speed to see what they were
saying. He said that during the entire QSO neither one of them ever got
the other station's call correct. :=)
