The problems are unrelated, so your conclusion doesn't make sense to me. 
The PL decoders are determining the frequency of the tone, whereas the 
brain, and a CW decoder, are listening to or looking at the envelope. 
Moreover, the filtering in front of the decoder will be most effective 
on the lower frequency tones, again because of the greater percentage 
bandwidth as compared to the difference in Hz of an interfering signal.

FWIW, my CW pitch is usually set around 500-550 Hz unless a guest op 
changes it.
