Quite the process,compromises,and attention to detail of materials taking huge amounts of time invested.Doing this with many different types of bows had to take even more time,and as accurately as can be done I would say given the type of materials used.More than most will do and many have benefited from your research.Even FG bow makers too.
Still making and shooting a broke in primitive bow that took very little hard set from tillering[under an inch] and shows very little soft set[under an inch] after being shot a couple of hours are and have always been the priority.Reducing the amount of noticable hysterisis a bow has.Showing me the limbs are not stressed and will stand the test of time.Just like over by you.I have the luxury of shooting with a couple of bow makers here especially one that does quite extensive testing himself.
There are definitely designs in primitive bows that will out shoot common FG bows here,but if their designs are made properly they still can get the upper hand over a longer stretches of time is what we've found just because of their practically 0 hysterisis materials.Not very noticable but still noticable.Even then some FG bows designed to the edge can and will fly apart or delaminate a bit with a fly apart on the horizon....lol.
