DOF scale issue. X-T20 with XF14mm

[mahidoes]

Both the lens and Camera running latest firmwares. 

 

I'm focusing manually in my XF 14 achieve HFD

I found DOF scale in viewfinder as well as in LCD (Blue bar) is inconsistent and I feel like it's shifting shot by shot.

Should I relay on DOF marks in the lens or in the LCD?

IF I'M TO RELAY on the lens marking can I ignore the shifting blue bars on EVF and keep shooting?

Alternatively I can ignore  both marking and use DOF calculator app and manually focus as I did in my canon live view in the past. Although XF 14 lens appear to be mechanical focusing it's fly by wire . So still changing focus indicators in viewfinder / LCD haunts me even if I do in the old way. It's difficult for me to check my focus every shot prior to click the shutter.

Please how do you focus you xf14mm for HFD?

if I don't find enough help I'm going to keep AF and focus on where I need to achieve HFD every time. But this is kind of work around idea.
