What is it that makes the 1701P trigger group "work" well?
I am starting a project that will require a trigger assembly that will reach quite a way up through the lower receiver to hold back the hammer.
I assume the geometry of the links latching surface relative to the sears pivot point is the most critical feature. I have access to waterjet cutting but the cost can be prohibitive so hope to limit design revisions. Setup is a good portion of the cost so I will probably CAD 3 versions of the assembly with two copies geometry slightly modified to either side of what I guess as the optimum design.

Definitely following this thread. Now you've got me curious as to what you're going to be applying it to.

I'm a peaceful man and prefer the pursuit of peaceful sports. Those involving teams and balls of any sort tend to be deleterious to one's body and promote violence by both spectators and participants. The shooting sports, however, tend to promote self control and are peaceably participated in by those who know that their greatest challenge is their need to continually hone their own abilities.

Your design looks like it would have a very long trigger pull.... In the 1701 trigger, the 1st and 2nd stage screws contact the toggle close to the pivot, the shelf that trips the sear is in between the screws in distance from the pivot.... In your trigger, the screws contact the toggle about 3 times as far from the pivot as the sear shelf.... so it will take about 3 times as much movement of them to trip the sear.... Since your trigger proportions seem similar, you can expect about 3 times the trigger travel.... IMO....
