So this looks like a case of MYTH BUSTED! Apparently a Cheap ERC belly/Sinew backed bow can hold extreme reflex and be a real shooter. Not that we know for any certainty that the artifact bow was either a real shooter or a tourist trinket, ...but there seems to be MUCH LESS reason to suppose that it was anything but a real and functional weapon. BTW - Who would ever bother to lay up such a heavy bunch of Sinew on a trinket bow? I'm guessing the guy that assumed such a thing had not ever spent time processing sinew, ...and had almost certainly not done so with primitive tools!
ERC loves compression work don't it!? This is a very beautiful bow sir.
