I wanted to test the mod on foundries in the Lab Scenario with the default setting (+50% per level)
Testing with the Copper Ore Melting recipe, common, uncommon and rare works, making 500, 750 and 1000 molten copper
but epic and legendary makes 1020 molten, instead of 1500 and 2500 (legendary is two levels)
I think that for one tick the output buffer is completely full, and the next tick it has time to empty a little bit, but doesn't continue afterward
