[Elecraft] K2 KAT2 tuner SWR readings

[Ivin Flint]

With a little help from Don W. I seem to have my KAT2 up and going pretty good and it sure is nice to have a built-in auto tuner again.  My last QRP rig was a Icom 703 which also has a nice auto tuner.  

Here is my question.  There are three ways to see SWR from what I understand.
1) holding the tune button putting the tuner into tune mode and seeing where the SWR ratio ends.
2) holding RF/ALC& Tune putting it into Pout mode and seeing forward/reflected power.
3) going into the menu X.X-1 mode.

On my off center fed dipole I read on 20M  the following in the above mentioned order.
1.8 - 1
5.4 f  -  .8r
1.8 - 1

So I guess the x.x-1 is directly re-displaying what was displayed at the end of a tune function, but I don't understand why I get two different readings between the Pout reflected .8  and the other two 1.8.  Is it just my own mis-understanding of what is being shown?  .8 and 1.8 is exactly 1 off, but I'm obsessed right now with wanting to be sure the tuner is working as it should and I can trust that it is doing it's job.  

As soon as I am confident things are working right I want to go out in the FREEZING outdoors and try my random wire.  I can't wait to get out into the woods again and enjoy the tuner.

Thanks as always.
