Possibly the fastest way to set the LPP (a.k.a. NPP)

With a LASER level on the panorama head and a with camera Live View Mode set on...

Note: only step1 and step 2 are needed.

 

A small home-made bracket supports the LASER leveler which beams then upwards. It could be fixed on the base of the level box with double side tap but the steel made bracket on the photo is simply attracted by the leveler integrated magnet. The width of the bracket base is 29,95 mm: that is to fit just tight between the rails of the NN5 on the top of the arm.

Step 1: The LASER level is put on the panohead (duration ~1 second)

This is how the whole setup looks like (if the camera isn't yet mounted). You may see the vertical trace of the LASER planar beam on the black surface of the NN5.

Mounting the camera

If this wasn't already done before step 1, of course:-)

 

Note: At this stage you shall see a bright red LASER dot right at the center of the LCD screen (on the back of the camera in Live View Mode). If you rotate the side arm of the panohead (even slightly) away from the vertical, the dot shall disapear from the display screen.

Step 2: Setting the No-Parallax-Point aka NPP (2 to 10 seconds)

Rotate the arm to put the camera at the required oblique angle. Here, 45 degrees is selected. The dot is not seen on the LCD:

Now with the minimum lens aperture opening being set (e.g. f/22), move the camera slowly back or forth and look on the LCD in the live view mode of the camera. When the red LASER bright dot is visible on the LCD, stop moving: the NPP is set. Lock the screw knob. That's all there is to it.

Optional:

You may look on the side of the lens to know where the NPP is located

...and have a look from the front of the lens (the oblique angle between the lens axis and the LASER beam is 60 deg on this photo)

 

Would a bulkier laser level work as well as this compact model?

Yes: I have simulated such a thing by inserting some wooden block underneath the LZR3 and there is no apparent difference at all in the result:
