Pentax specifically said that the camera was using information from the SR system to do the stacking and get super resolution. That specific information is supposed to be encoded in the RAW image. It is supposed to give better results than standard super resolution.

I always took the SR information as just additional help with the alignment aspect, like another way of getting to the same place as PS might manage when you hand over non tripodded shots for alignment. Clearly PS doesn't use SR information to do it, but its an advanced program and not a camera so can manage that feat fine.

The thing about super resolution is you can use 4 files or 20, with Dynamic PS you get 4, and if one is not a great frame (just like how in Super Resolution you can get a pesky frame that ruins the rest), then it's not a great Dynamic PS shot.

Pentax have also said the best pixelshift is still (and always will be) a tripodded one. Really I just feel that Dynamic PS really is just a SR shot, processed in camera at the time, and it may turn out great or may not, and whether you want to use it or not and be locked out of the camera for a minute or so might not be an issue one day and another time it is. Where the feature fell down for me was the fact I always leave my house with a small tripod for my landscape work, for clouds or waterfalls etc. I tried Super Resolution a few times, it works well, but the computing time is off putting. Really for the sake of taking a small tripod with you and using normal pixelshift, the results and time spent on it all, total win.

What do you mean by "standard super resolution"?

"Standard super resolution" depends on tiny motions of the camera between frames to get every part of the image sampled by every color on the sensor. It then cross-compares the frames to estimate the frame-to-frame motion, aligns all the mosaiced Bayer filter data together, and resamples all the data into an output frame.

I'd wager that the K-1ii is doing a lot more than "standard super resolution" because standard super-resolution needs a lot of frames to get decent results -- four is not enough. The chance that a person's random movements of the camera make each part of the image have some data from red, green, and blue sensel is quite low after only four frames.

Most likely, the K-1ii is doing something to measure and control sensor position to get better results than random motions and standard super-resolution could produce.

I beg to differ. I have seen 4 done very well on multiple occasionas vs 20 or so where there appears to be no real greater perceived improvement. I myself have done 4-20 and can confirm that finding myself. YMMV.

I have heard some find the Dynamic PS really quite poor, however that's just speculation. It would be nice to see a real indepth review if Pixelshift vs Dynamic PS vs Super Resolution and compare the results and factor in all the pros and cons, would be a good read I rekon.

Ok, "standard super resolution" is not Classic pixel shift, nor Dynamic pixel shift modes...
What about Topaz Gigapixel AI software? Has anyone tried? I used it to make 60cmx90cm (23.62x35.43 inches) @300ppi photo enlargements and I found them fine. Both from 20mp (EOS 6D MKI) FF sensor and from 36Mp Pentax K-1 PS mode on B&W 24x36 roll film scans.
Is Standard Super resolution a better result?

I've heard Topaz Gigapixel AI is excellent.
