Last time I checked, CW dits are one unit length duration, and the 
spaces between dits within a character are also one unit length. Most 
keyers these days can have the "weight" adjusted, so that the proportion 
is not necessarily exactly what I have said. However the "standard" 
timing of a string of dits would result in 50% duty cycle.
