Flavio,

Actually, with care (meaning that the relative amplitude
characteristics of the added waveform are well known) the possible
added precision has no inherent upper limit.  I think that the reason
for this can be appreciated from my two prior postings.  But, if not,
I can try to explain further why this is so.
