Dan,

I don't recall this particular question being addressed in the owner's
manual.  However, based upon basic RF receiver and repeater technology,
I would bet that the RF signal is repeated almost instantaneously and
any transmission delay would probably be rejected by the receiver just
as it rejects wave reflections and ghosts.  Remember, RF repeaters are
very fast, not as slow as the rest of the X-10 response times we all
love.  I don't know for certain that these particular devices operate
this way, so it could be that I completely made all of this up.

The proof is in the pudding though, my SR731 works, I don't seem to have
any X-10 signal crashes, my lamps don't dim twice.  Just plug in one of
your RR501s and see what happens.
