Dale, could you comment on why you use (or it appears so anyway) a 9V battery to power the R2LC instead of track power? I realize it allows you to lift it off the track and take measurements anywhere. I figure a track-powered R2LC installed in a typical engine or accessory car has a steel chassis connected to the outer rail and attendant wiring/harnesses. It seems this would present a different signal receiver environment, ground plane, shield to the antenna, etc. than a battery-powered receiver on a plastic flatcar bed.
I'm wondering if the readings will substantially vary depending on the signal-receiver design. OTOH it may be a your-mileage-may-vary situation where as long as you have a tool to improve your own layout it doesn't really matter if readings compare to another layout...
