What's the offset loss of the male short in the 85054B calibration kit?

Question asked by drkirkby on Nov 19, 2015
I'm trying to define a user cal kit in an 8753ES so I can use my 85054B cal kit - a bit of an overkill on a 3 GHz 8753ES!  I've been comparing the 85054B data for the PNA given in this HTML file on the Keysight web page

http://na.support.keysight.com/pna/caldefs/PNA/85054B.htm

and the data in my 8720D's firmware, which unlike the 8753ES, has the 85054B in its firmware. There's a small, and no doubt insignificant difference in offset loss of the male short between the data in the HTML file above, and the what's in the firmware of my 8720D

* 1.1273 GΩ/s - at http://na.support.keysight.com/pna/caldefs/PNA/85054B.htm
* 1.1268 GΩ/s in the firmware of the 8720D. 

I'm sure the difference is pretty insignificant, especially since the 8753ES is a 3 GHz model, but since I need to stick a value in the user kit, I might as well put the most accurate estimate. I'm assuming the calibration kit definitions have been updated since the firmware for the 8720D was last updated, but I want to check that the HTML file is right.
