Just wondering what's the fastest values I can input. I currently have all the speeds at 999

  "Speed Multipliers": {
    "global": 999.0,
    "electric.furnace": 999.0,
    "furnace": 999.0,
    "furnace.large": 999.0,
    "legacyfurnace": 999.0
  },
  "Fuel Usage Speed Multipliers": {
    "global": 999.0,
    "electric.furnace": 999.0,
    "furnace": 999.0,
    "furnace.large": 999.0,
    "legacyfurnace": 999.0
  },​
