None of the copies have any multipliers except the large IND production bonus, but ignoring that, it's fair to consider the normal base cost as the true cost of the copy national wonder: So the HE copy is 200 base hammers no matter what, OR, Forges, Marble is removed as a production modifier. I've also removed the IND production bonus from all wonders. So the base HE is only affected by marble.
With that in mind, it's 330-ish/400 hammers and +200% modifiers on units v. 360 hammers and +150% on everything. Best case scenario, and both HE hit 25 base hpt for a unit per turn, what is that? 50hpt adjusted? So the forge example needs to make something like 200 hammers between 6 cities to come close to the best case scenario for the HE. Everyone knows that isn't happening. Unless slavery is still being used, in which case forges are going to be contributing about 5-6 hpt extra. But then everything starts getting to complicated for a back of the envelope calculation.
I agree that it does not look like a dead trait at all. I'll be interested in seeing if someone can get two HE up and running in 20+hpt cities by T110 here.
