Seeking guidance on K-3 Auto ISO and Program Line settings

As I'm sure most K-3 users have discovered, there are two settings which seem to overlap to some degree: Auto ISO sensitivity (slow, standard, fast) and Program Line (Auto, Normal, Hi-speed, DOF Deep, DOF shallow, MTF). Is there any insight as to how these two functions relate or interact? Are there combinations that should be avoided? TIA.

Auto ISO will operate as you define in all modes where applicable (av,tv etc)
Program line will only have any funtion in 'P' mode and then effects both shutter and aperture in line with selected program line.

The selected program line will not nescesarily effect ISO so they do not overlap at all, changing ISO profile will effect how fast the program line would adjust ISO to help achieve a exposure soluttion matching your stated preference Auto, Normal, Hi-speed, DOF Deep, DOF shallow or MTF . Just as it woudl in AV or TV mode.

I use AutoISO with Av mode. With my DA*300 it will give me 1/400 as slowest shutter speed before rising the ISO with Normal. With Fast I get 1/800 and slow 1/200.

My camera is set almost constantly on Tav which gives you auto ISO while allowing you to control shutter speed and aperture.
