Heath, As others have indicated, the LokProgrammer is faster because it only works with ESU decoders. Kinda like that question you asked about function labels and BLI. Single manufacturer means special methods can be used. DecoderPro uses the NMRA method because it has to work with a wide range of manufacturer decoders. I have read that there is faster reads IF (1) you have a Railcom enabled command station AND (2) the decoder is Railcom capable and enabled. It also allows reads using POM.
