Just a few facts about the tool and guide jig. My stuff is a little older and badged Hoffman but I think it's probably the same otherwise. Mine didn't come with instructions when I bought it used. I found a manual online but it is pretty useless.
The critical number to remember for the tool is 65mm. That's the distance between the centers of the drills and the outside edge of the guide jig. The guide jig is close to exactly 64mm wide but I can't figure out how to make use of this dimension. If you want to drill a line of holes 37mm from the front edge of a panel, the edge of the guide jig would be placed 102mm in from the edge (65+37).
The tool can drill two (or even 3) rows of parallel holes on 32mm centers without repositioning the jig. Why you would want to do this I can't figure, but it's easy to do. If you set the adjustable fence to 0 height you can flip the tool around and drill your second line of holes at 97mm from the edge of the guide jig (65+32). The fence can be moved out 32mm and a third row can be drilled at 129mm.
I have not been able to figure out a sensible and quick way to position the guide jig for drilling the back row of a base cabinet on perfect 32mm centers for drawer hardware. Perhaps there is something I am overlooking.

I regularly use the guide templates (I have the short and the long) for drilling rows of holes, as well for indexing dowels on longer runs on large panels.
One trick I learned is to make plywood cleats to set the distance of the template from the front edge of the work piece. So, for my mobile Systainer modules, I have one cleat that indexes the template for the front row of holes, and a second cleat that indexes for the back row of holes. I simply slide the cleat against the front edge of the work, slide the template again the cleat, then tighten. Remove cleat, then start drilling holes.
I have another set of cleats I use for indexing the template for properly aligning dowel holes on larger panels. One cleat for dowels drilled in the face of the material, a different cleat for dowels drilled in the edge of materials.
I LOVE the ability to infinitely adjust the template. I drill all of the 5mm holes on my Systainer modules in 16mm increments. So, I drill everything at the standard setting, adjust the stop by 16mm, then drill everything again. This allows me to double the density of holes and potentially fitting extra shelves in a given cabinet.

Is that the sweet sixteen method?

Sounds great Tom, I am still into the Dirty Dozen method.
(it takes a dozen tries to get it right, usually I give up at try #11...)

I happened to be in my shop for a few minutes this afternoon so I was able to create a rough mock up of my procedure for using the cleats to index the guide template for drilling holes. This first pic shows my two setup cleats on the left, a panel I've already drilled, and the DD40 guide template on the right  First step is to place the cleat for the first row of holes against the front edge of the panel.  Second step is to place the guide template against the cleat and tighten. If you look closely you can see that my template is still set to the 16mm offset to double the hole density.  Next remove the cleat and drill away!

Next, I switch to the cleat that indexes the template for the back row of holes. Again, slide the cleat against the front edge of the panel:  Next, slide the template against the cleat and lock in place  Again, remove the cleat. This time I drill on the other side of the template.  I apologize if some of the images are rotated incorrectly, I'll correct them the next time I have some time at the computer.

Thank you Tom! This saves me the trouble of coming up with the same solution. I will definitely copy this. Have me some shelves to build and I have been putting it off for a few weeks so this will come in handy for sure.

"The guide jig is close to exactly 64mm wide but I can't figure out how to make use of this dimension."
Same dimension as the offset - to make it easier to mark a parallel line on your panel where you need the guide to be clamped, instead of measuring. Go to approx the 7 minute mark of the video -
