There are different calculations that can be used to compute Doppler, and most of it has to do with how temperature and humidity are accounted for.

I just plan to accept that the RCS reading will be a little slower than when I take the file home and click the lines myself.
Who knows which one is really more accurate...
RCSpeedo is great for a field reading and for applications where you don't need dead nutz accuracy, which is the case for most folks.
Thanks for confirming that. Hopefully the author will make improvements with time.
