Smelting ore to plates direct or via ingot/molten

[pieppiep]

I can melt copper ore to copper plates on a ratio 1:1
I can melt copper ore to copper ingot 5:5, then to molten copper 3:3 and finally to plates 2:2
Both give me the same number of plates for ore.
What is the purpose of the longer chain?
The only thing I can think of is when using productivity modules it gives more. Is that really all?

You'd think it'd be at least faster but not really. Processed ore gives +50% without modules, but that thing could be much faster, it should give like batches of 20 copper.

I'll just leave this here.

With the fully developed Angel's smelting, you get the following:

For IRON, TIN, TITANIUM, STEEL, you get this:
- 4 ore -> 1 cart = 0.25 cart/ore
- 2 cart -> 12 pellet = 1.5 pellet/ore
- 4 pellet -> 5 ingot = 1.875 ingot/ore
- 3 ingot -> 3 molten = 1.875 molten/ore
- 2 molten -> 2 plate = 1.875 plate/ore

COPPER, SILVER, LEAD, ALUMINUM, GOLD, NICKEL, TUNGSTEN you get this:
- 4 ore -> 1 cart = 0.25 cart/ore
- 2 cart -> 12 pellet = 1.5 pellet/ore
- 5 pellet -> 5 ingot = 1.5 ingot/ore
- 3 ingot -> 3 molten = 1.5 molten/ore
- 2 molten -> 2 plate = 1.5 plate/ore

And SILICON is the best:
- 4 ore -> 1 cart = 0.25 cart/ore
- 2 cart -> 12 pellet = 1.5 pellet/ore
- 4 pellet -> 6 ingot = 2.25 ingot/ore
- 3 ingot -> 3 molten = 2.25 molten/ore
- 2 molten -> 2 plate = 2.25 plate/ore

Ah, I see now after some more research more options.
