The ETA with the above set up is useless for us and this is how it has been for over 12 years now. Any better recommendations to setting this up any other way? Wondering, if any of you out there uses PCMILER Rail for the Rate Service calculations ?

Note that - we do use PCMiler Rail for the external distance engine calculations but have never used it for any Rate service calculations. Any i/p is appreciated.
