Maybe, the early information that shift is +/-2mm in every direction was correct and the newer, corrected info (1mm) is wrong?

I saw somewhere that it was ±1mm with SR on and ±2mm with it off. Not sure if this was a further wrong guess or maybe the source of the confusion in the first place.

No, some one was confused with auto level adjustment.

Composition Adjustment is +/- 1mm (both X & Y) at 0.0625mm increment.

Auto Level Adjustment is +/- 1 degree with SR ON;
and +/- 2 degree with SR OFF.

What is auto level adjustment?...would it level the capture up to 2mm even if the camera is held at an angle ?

2°, not 2mm. But yes, it can do that (optionally). You can also just have it show the level and not actually rotate the sensor, if having the camera do it for you doesn't seem right.

So, 1mm in 16 steps.
2° requires 1mm, so this is consistent.

Can anybody confirm my experiment above? It's fun, actually. A table top will do as well

Because if true and if the SR wasn't reduced in size, then this would be strange.

It should be pretty simple to test this. Just divide the frame by 15.7 (the height of an APS-C sensor) and you could see what portion of the frame is 1 mm. Would that be enough to capture the top of a building when the camera is leveled parallel to the ground? It may be in some cases.

Prog.

One easy way to visualize a normal 6"x4" print, the maximum range of adjustment (one extreme to another) is about 1/2 inch both vertically and horizontally.

Where did you get this?

K7 composition adjustment = slight shift effect?
