This is one of the major reasons advanced for using Dual Frequency CW.
Being basically syncronous, you know where the transistions are to fall and
so if a 2 dot length segment breaks into 2 or 3 pieces we can still deduce
it is 2 dots with signal dropouts since it never went to the dash frequency.
And visa-versa with the dashes.  But it also makes it more difficult to
figure out the speed from a random or unknown source.  Is that one dot at 60
seconds or two dots at 30?

Forty years at this kind of stuff and I am still waiting for my free
lunch<G>.
