The "S" in RST system on CW was never intended to be an S-meter report.  In 
fact, the RST system and it predecessor were in place long before most hams 
even had an S-meter on their receiver. The signal report was designed to be (an 
inherently a subjective) evaluation BY EAR of the signal by the person doing 
the listening on a receiver.  Pick up an ARRL handbook and review the 
definitions of each component of the RST.

Under certain conditions, for example with some of the receiving antennas 
commonly used on 160m, a valid signal report might be 589 or 599, even though 
it only registers S2 on the meter. An S-meter report can be made more 
meaningful by reporting the reading with the presence of the signal, and again 
with the background noise in the absence of the signal.  For example, "you are 
hitting ten over nine on the meter, and the background noise is S-3".

IMO, one of the weaknesses of the RS(T) system is the nine levels of signal 
strength.  Whoever originally conceived of the system got it right with five 
levels of readability, but missed the mark with nine levels of signal strength. 
It is unrealistic to make a clear distinction between, for example, S6 and S7.  
RST is an adaptation of the old QSA-R system, which likewise had superfluous 
nine levels of signal strength report, represented by "R".  A five-nine report 
would have been expressed as "Q5, R9", and this terminology was still heard 
from old timers as late as the 1960s.

Five  levels of readability and five levels of strength would be much more 
meaningful, and less subjective on the part of the operator, than nine. 
French-speaking military communication uses a 5 by 5 system for signal reports, 
and the expression has crept into ordinary (non-radio) language to mean "(I 
hear you) loud and clear": "cinq sur cinq".

Regarding contests, since the signal report has been declared meaningless, it 
should be eliminated altogether.  In any case, in the rare occasions that I do 
participate in a contest, you can expect an honest signal report from me.
