As Matt said, Feff does not always calculate absolute energy reliably,
although John and his gang are certainly making good progress on that
front.  I think there is ample evidence, however, that Feff does a
fine job on *relative* energy.  You calculation appears to be
suggestive of both of those points.  I think you can, with confidence,
shift the Feff calculation by a few volts and carry on.
