747-400 Slip/Skid Indicator

[NSEU]

I have been told that the slip/skid indicator on the PFD will not go beyond the edge of the roll pointer. However, my training notes has a diagram showing otherwise.



Also, during a CMC IRU Ground Test, I have seen the skid indicator momentarily go more than a bar length beyond the roll pointer.
Admittedly, test conditions can generate some spurious indications and notes are often wrong.

Has any 744 pilot here seen the skid indicator go beyond the edge of the roll pointer? (in the sim or in real life).

Thanks
