Well a buddy, with no prior experience with the DOMINO just did this - on all the mitered corners of a 2x4 gate - 5'6" wide by 7' tall.

He used the 10mm "bit", "22" setting on the center on stock width preset (center of resulting mortise is 11mm off either rerence face) "outrigger pins set at 100 mm from mortise long axis center line.
Total time - with no prior experience - from first cut to last cut *8th mortise) on one part - with mitered ends- was 2 minutes 22 seconds, including clamping and unclamping the part to flip it over to use the other reference face for the second pair of mortises. 8 sets if 4 mortises cut and only two needed tweeking. The tweeking was required because two of the part - green pressure treated 2x4s were slightly bowed so the "knife edge" of their mortises weren't square to the face of the boards. Because the DOMINO was referencing off that "knife edge" the resulting mortises were off by maybe 1/32nd of an inch - enough to make the joint not line up. A pass or two with a file on the knife edge and 30 seconds to recut the erroneous mortises and things fit.
Did I mention that the parts were 7' and 5'6" long? Imagine doing the same mortises with even the Leigh FMT or MultiRouter - mortises in end grain, on a mitered face - of a 7 foot long part.
I guess I gave the impression that the DOMINO could ONLY USE the "presets". Actually, the fence range is 5mm to 30mm from fence to mortise centerline using the provided scale on the DOMINO So, as long as your part is thicker than 2.362" (2x30mm/25.4mm/inch) you can center the mortise on stock anywhere from .394" to 2.362"
Regarding doing a pair of mortises, one centered on a 2" leg and the other centered on a 1" apron - no big deal. Use the fence to mortise centerline scale and set it between 25 and 26mm for the mortise centered on the 2" leg and between 12 and 13mm for the 1" apron.
The DOMINO is an elegantly simple tool once you understand the parameters you can use, what they do and how to do it. The metric conversion to the more familiar imperial system muddles the the water a bit and my shortcomings in communicating what makes the DOMINO such a significant addition to the wodworking tools and machines arsenal shouldn't muddle the waters further.
