Not in any, really. I'm not aware of any (published) experiments having
been done to establish decoding thresholds for it, which I could use
to put it in the table.

Compared to regular CW transmitted at the same (peak) power, DFCW has
about 3 dB more average power because the transmitter is on continuously,
so just because of that, it should give better performance at the same
_peak_ power level. However, whether the performance difference is more
or less than 3 dB, and thus whether it is better or worse than CW at the
same _average_ power (as normally used for Eb/N0 calculation), is harder
to predict.
