Some mods add machines that one input can create 2 or more outputs like the machines in thermal expantion. Can you add it so that the recipe map for determining emc values can handle recipes with multiple products?

Ha, if you could come up with a way to calculate the values, sure. But I don't think you're gonna find a way :P (hint: it's impossible)

Hint: you can use lowest ones.

There's no way to find the ratio of the values for the output. Just splitting the value is not an option.

Full value minus known value?

But we don't always have a known value, especially with the Thermal Centrifuge from IC2. On top of that Thermal Expansion has a chance of getting the item, should we just divide by that chance of getting the item? It's a way to get more recipes known (but certainly not all), but it requires a lot of code to get it working and the amount of multiple output recipes to too low to make it worth the effort, manually adding them is less time consuming.
