SWR reading different in ATU Radio Panel in SmartSDR vs Tuner Genius XL

in Tuner Genius XL

Running 8400M / v4.0.1
Both the ATU and Tuner Genius tune my antenna
When I tune with the ATU for 20M for example I get 1.19:1 (TGXL off)
When I tune with TGXL same band antenna, I get 1.05:1 (TGXL on and ATU greyed out) and the ATU SWR will show 1.20:1.

So, when tuning with each respective method, should I go by its SWR reading and disregard the other?

This may be OCD on my part…

Thanks, and 73's

Bill

    Hi Bill, You will always get slight variations when the sample points are at different places in the line. Also, there is no practical difference in 1.05 vs 1.20. Either match is well within the ability of the equipment, and will make no discernable difference to the listener at the other end.

    Len,

    Thanks for your response. I am training myself to not be concerned with these slight variations.
