I noticed one of the parameters in your documentation is the "scale factor." I've known for a long time that the number of motor revolutions per distance traveled is embedded in the loco's "personality file."
Could you use your program to tell me which MTH locos have the lowest gear ratio (or at least the maximum number of motor revolutions per inch?) This is super-important to the operating characteristics of a loco, but it's not usually published in the specs. Being able to read it from a downloaded "personality file" might save me the need to take it apart and count the revolutions manually.
I also thought about inferring the ratio by swapping the file into a known loco, and measuring the magnitude of the error in speed and distance, but this is still a lot of work. Thanks!!
