Anvil crafting formulae

[Sitting_Bill]

Sorry to make another thread about this, but it still hasn't been answered properly (and the thread is now off the bottom of the page, for quite a while).

My sqrt(str*smithing) is plenty high, greater than everything else.

So it seems the formula for armour, at least, is (3*AvgMetalQ+AnvilQ+HammerQ)/5, from my limited data. Can anyone actually confirm or deny this?

When there is more than 1 type of material for the craft - eg soldiers sword or B12, what is the formula?

Perhaps (3*AvgMatQ+AnvilQ+HammerQ)/5.

However, which AvgMatQ... Is it (a) (AvgMetalQ+AvgBlockQ)/2 or (b) the straight average of all the pieces of material. In other words, is the average weighted by the number of pieces of material used, or not?

This makes a huge difference for a B12, especially...

Thanks
