What are the advantages (if any) of using this instead of plugging your data points into an excel graph and getting a polynomial best fit equation to transform your distance into an rpm?
The biggest advantage was it made tuning very easy. Take the bot to the practice field with some balls, fire away, and record the range/RPM information into the TreeMap if you like what you saw (we actually had a version of the software that let the operator do this with the push of a "commit" button, but we ended up doing it all by hand just to sanitize the values). No need to fire up Excel.
