[Elecraft] 10 mHZ external reference VS the K3S's optional KTCXO3-1

[Bob McGraw - K4TAX]

Yes, I've been following this as well.  And to that end, I have a 
commercial GPS Disciplined Oscillator that is used as a reference for 
the test equipment in the shop.  In checking my K3s I find, with the 
optional TCXO, the accuracy is typically +/-2 Hz on all bands.    Few if 
many other transceivers will display or maintain this stand-a-lone 
accuracy.  So I ask, what's the obsession with accuracy better than this 
for amateur use?

Or is this just a way to achieve more accuracy at less cost than the KTCXO3 ?  Isn't the K3S better served with its own oscillator?  What am I missing here?
